Server Load, And Tracing Httpd Processes

Feb 28, 2008

I have a server that has server load showing at 25-40 (once it was even 53!), running like that for hours. The server has 4 cpus - and yet the sites on the server seem to run fine when I check them. What I'm wondering is, what exactly is load in this context; and how can load run so high like that without the server crashing?

According to top, the load is caused by httpd processes running under user 'nobody', that often take up double digit CPU percentage.

Does Apache always run under 'nobody'?

Is there any way to trace an httpd processes - which account it's for, or which physical script or URL is calling it?

And for top itself, the TIME field on one server of mine is in the format xx:xx (e.g. 3:25), on another it's TIME+ and in the format xx:xx.xx (e.g. 30:02.77). What exactly does this mean? I would asume it's minutes:seconds and minutes:seconds:hundredths, but while watching top it doesn't seem to correlate with that.

High Server Load - Httpd Processes

Mar 23, 2008

a topic long time ago that my server load is frequently high.

I'm talking about something like this
Server Load 158.86
Memory Used 28.2 %
Swap Used 99.57 %

[url]

The only way to solve this problem is to identify the load earlier and kill all httpd process. What I did was

#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.

On previous thread, I tried to update mysql & php and it works,

Right now again I am experiencing high server load again...

I'm very sure it's caused by httpd but I am still unable to find out the real cause of the problem and which account user is the culprit for causing this high load.

Can someone assist me by telling me where/how to begin with?

Tracing Server Load

Mar 4, 2008

what is causing a high serer load (25-30% cpu usage average).

Using cpanel 11 / centos 5 / php 5 / mysql 5 / phpsuexec

root@server3 [/proc/8052]# ps waux | grep -c exim
28
root@server3 [/proc/8052]#
root@server3 [/proc/8052]# ps waux | grep -c exim
27
root@server3 [/proc/8052]# ps waux | grep -c mysql
3
root@server3 [/proc/8052]# ps waux | grep -c httpd
46
root@server3 [/proc/8052]# ps waux | grep -c php
3
I am having a hard time tracing who/what is causing the high load

Tracing Server Load

Mar 8, 2007

What is the most effective, surest way to trace server load (centos / cpanel, shared hosting environment)? I'm aware of top and top -c but I'm looking at it and nothing shows high usage, yet whm server status shows about 12-20% cpu (dual xeon box, 4gb memory). Disk usage is 32% (10k scsi, 300GB) I've attached 4 samples of top -c

Understanding Netstats - Tracing Processes

Jul 5, 2008

I was checking my netstat and I saw something like this:

Proto Recv-Q Send-Q Local Address Foreign Address State User Inode PID/Program name
tcp 0 1 192.168.30.98:40493 207.45.xxx.xx:3306 SYN_SENT 48 3130522 5339/httpd

tcp 0 1 192.168.30.98:40502 207.45.xxx.xx:3306 SYN_SENT 48 3130994 6732/httpd
tcp 0 0 192.168.30.98:47493 65.55.xxx.xx:80 TIME_WAIT 0 0 -
tcp 0 0 192.168.30.98:47494 65.55.xxx.xx:80 TIME_WAIT 0 0 -

tcp 0 0 192.168.30.98:47497 65.55.xxx.xx:80 TIME_WAIT 0 0 -

I see that there are some connections from my server to some remote mySQL server, and I am curios to know which script is running them. (192.168.30.98:40493 207.45.xxx.xx:3306 5339/httpd)

I try through lsof but it is not that it points directly to the website running this connection.

I also see some strange connections like:

Code:
tcp 0 0 192.168.30.98:47493 65.55.xxx.xx:80 TIME_WAIT 0 0

I want to know if this is some uncontroled script in my server.

Tracing Cause Of Server Load Spike *after* Reboot

Apr 9, 2009

I have a cpanel, centos server that had to be rebooted due to the high load spike. I was unable to ssh in nor enter whm prior to the reboot so my only option was of course to reboot the server.

Now, I'm trying to trace the cause of the spike. RTG graphs show no indication of a ddos attack.

Inside whm, CPU/Memory/MySQL Usage shows no reds nor yellow warnings either except red for gzip (backup process) at 19% CPU. I doubt this is the cause.

This is from /var/log/messages of the logs slightly before and after the reboot.

Code:
Apr 9 13:31:49 server pure-ftpd: (?@70.250.201.162) [INFO] Logout.
Apr 9 13:32:05 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3
Apr 9 13:32:28 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3 .......

Plesk 11.x / Linux :: How To Stop High Number Of Httpd Processes Crashing Server

May 17, 2014

Our server is running; Plesk 11.0.9 and CentOS 5.7 it has a Q8200 CPU @ 2.33GHz and 2GB of RAM. Now there are just two websites on the server plus a couple of redirects/forwarding domains, although lots of domains are still on the server but turned off in Plesk. Both websites are OSCommerce sites and I just need to keep these sites going until the end of the year when we will switch to our new Joomla based website.

We have seen an increasing number of server crashes and after various checks of the logs, fitting a new BIOS battery, check of the hardware by EasySpace who host the server, installation of ClamAV, LMD and RKHunter (which did find some Trojans and Suspect software), I have traced it down to some external Http activity that is taking all of my CPU time and RAM. Here is a screen capture of the Htop listing and when I killed these processes the CPU and RAM went back to normal. The problem is that I usually have to restart the HTTPD service and sometimes things get so bad that the server crashes and I have to request a power cycle.

Server Load :: Of Simultaneous Processes Should Not Exceed 5

May 1, 2008

In learning that some hosts seem to be tightening shared hosting specs, I'm wondering what a 'simultaneous process' is... as from this clip: 'number of simultaneous processes should not exceed 5'.

Is each part - for example, graphics and includes - of an individual webpage a 'process'?

Server Update, Too Many Apache Processes But Low Load

Apr 24, 2007

I have 2 almost similar webservers:

debian 3.2, P4 3GHZ, 1 Gb ram, kernel 2.6, apache2, php4

Initial apache2.conf:

Code:
Timeout 4
KeepAlive Off
KeepAliveTimeout 2
ServerLimit 1500

<IfModule prefork.c>
StartServers 10
MinSpareServers 10
MaxSpareServers 15
MaxClients 1500
MaxRequestsPerChild 3000
</IfModule>

I update the sources.list on server 1 to mirrors of the new debian 4 etc . I run apt-get update and apt-get dist-upgrade . A whole bunch of things get updated (it was long time ago that I did this anyway). After some troubles with /boot/grub/menu.lst the server boots ok, and everything is well. This server used to have loads of 15-25 at peak times, but after the update its running very smooth with loads of 2-3 at the same peak times. I dont know why exactly, as I noticed updates in OS , kernel version (from 2.6.8x to 2.6.18) , apache2 , php (4.4.4-8+etch1) , and I also needed to update eaccelerator from 0.94 to 0.95 .

A few days later I update server 2. Everything seems to go the same, although the kernel version stays at 2.6.8-3-686. I dont think kernel version at start was exactly same at server 1. But the new php version is the same as server 1, and everything else looks the same too.

But when peak times are coming up, this server starts to have troubles. It is quickly rising to total of 200-300 processes , while server 1 always stays stable at 60-70.

Server 2 also reacts slow if I click somewhere on the site. It takes 5-10 seconds to show a new page. However the load stays pretty low at 1-2 . I see no big cpu usage and also no big memory usage. I have the impression that this server 2 is somehow wasting a lot of apache processes and is making things hard for itself without a real reason.

When I check the seperate mysql database server, I also notice a lot of processes.

Around 200-250 whereas it used to be 40-60. Sometimes this adds up so hard, that all webservers are blocked because mysql has too much processes. When I check the mysql connections, I see a few dozen things like 'unauthen ip:port Connect login' just hanging. All of them have the ip of webserver 2. Those extra apache processes are somehow hanging on to the mysql server without really doing something.

I dont know what is happening, but this server is underperforming very badly now. I managed to limit the problem by drastically lowering ServerLimit and MaxClients on webserver 2 , but this is no real solution. The server is still slow, at least now its not bringing down the others.

My question : what should I check for now ? I noticed a different structure in the conf files in debian etch, maybe something new has a bad influence on my old conf files? Is there something wrong with the combination of kernel+php version? I have no idea, please point me in the right direction so I can learn from this.

Httpd Processes (9% Of Memory Each)

Mar 22, 2008

I recently modified my loadavg script to store in a database the output of a top command if there's ever server loads of over 1. Overnight I've had 12 such times logged to a database.

Upon inspecting things (I was expected there is a recurring problem), the top command reveals that there are always three queries running together which take over 30 seconds each, and take up ~9% of memory each:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
26119 nobody 25 0 73492 38m 4792 S 0 8.5 0:30.00 httpd
7313 nobody 25 0 76716 42m 4992 S 0 9.5 0:29.99 httpd
14212 nobody 19 0 70688 39m 4844 S 0 8.8 0:30.03 httpd

Is there a command that will tell me exactly what these processes are? Like in WHM's "CPU/Memory/MySQL Usage" whereby it says what account these httpd processes are coming from, and the actual page they are coming from as well?

If I could log these details (i.e. account and page these are coming from) along with the output of the top command, I can hopefully troubleshoot where this problem is coming from.

Httpd Processes Running Top Or Ps

Feb 5, 2008

so here is a simple question that i just can't seem to figure out.. when i run the command top or ps -auxw.. they show the httpd processes as the command httpd or /usr/sbin/httpd, but how do i know what file that is? is there anyway to find out what file that is actually getting executed or served?

Preventing Certain Processes From Using A Certain Load..

Jul 22, 2008

Is there a way to prevent a certain service from taking up a certain amount of load on the server?

Like, shouldn't there be a way I can tell gzip or exim how much server load they are allowed to take up on my server?

I know it may run them slower, but it will be for the better if I could set each one to only be able to have a max load peak or something.

Load, Bandwidth, Processes, CPU With Simple Php Script

Jun 25, 2007

I am thinking about making a little php file that will print a flash game with a link to my site below the actual game. Other webmasters can use this php file on their site to embed this game.

I'm on shared hosting with Bluehost at the moment. What will be the implications on bandwidth and CPU if these php files which serve the games become popular (get hit quite frequently per day/hour/second)?

High Server Load / High Swap / Lots Of Httpd

Feb 20, 2008

I have a cPanel server with 4GB RAM

My server hangs time to time, once or twice a day. This is the last status when it happens.

Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %

When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.

So I "killall -9 httpd", I had to do it 30~40 times

#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.

Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.

At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)

Httpd Failed - Sites Don't Load - Host Can't Help

Jan 9, 2008

The last 2-3 days my websites on my vps all started acting funny. Randomly throughout the day they will all just stop loading. If you go to one of my sites they will just load and load and load and eventually time out after 5 minutes.

To fix this problem, all I have to do is reset Apache in my WHM. Everything will be fine for awhile until it decides to stop loading again.

I've been talking to tech support for 2 days. They're out of options. They tried banning some IPs as they thought I might be getting hacked. They tried moving me to a different host machine. They've checked all my logs... there are no errors or problems with the vps. The server load is always very low. Memory is always very low.

I run about 15-20 websites on this VPS. Two of them are vbulletin (v. 3.6.4 and v3.6.8) and all the rest are wordpress).

My VPS is hosted with ServInt.

Server Version: Apache/1.3.39 (Unix) PHP/5.2.4 mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4
mysql (5.0.45-community-log)

I get these emails all day:
httpd failed @ Wed Jan 9 06:10:42 2008. A restart was attempted automagically.

I am completely out of ideas and options. Can anyone think of something? Think outside the box... make random suggestions. I don't care, I need to try something.

I most recently added 3 or so brand new websites to my vps about a week ago. However, they are just running wordpress so I can't imagine they're the problem.

I also have a few shoutcast services running on my server, but i think ther are fine

According to cpanel, yesterday I had this cpu usage (only showing the top process)

AOL Redacted Spam Complaints: Tracing

Nov 24, 2007

I have a customer that uses mailman to send out newsletters. For some reason he has a few users on that list at AOL that feel they need to report them as spam instead of simply unsubscribing or deleting. I'm on the AOL feedback loop, and receive these complaints each time he sends.

AOL removes (redacts) all traces that might make it possible to simply remove the complainer, instead making me have to go in and trace the mail. Ok, privacy and all that. Fine. Unfortunately, since he has a few hundred AOL addresses on that list, it's nearly impossible (AFAIK) to figure out who it is so I can remove that user (or three).

I've searched through the mail logs using the message ID and timestamp, as well as grepping for AOL in the results. This has narrowed it down to about 120 addresses. From here I'm stuck. Can anyone recommend something else to try in order to narrow it down further? What am I missing?

Here are the headers that came with the complaint, edited for privacy.

VPS- Server Processes Not Getting Killed

Apr 23, 2008

i am facing slight problem with one of my VPSes. It had happened earlier also but had got resolved automatically.

Please see this screenshot: [url]

i know that the server load is not that great to cause this much SWAP usage. i think this is because of the processes not getting killed.

UPDATE: here is the screenshot of my other server with the same provider. which is not really overloaded but i think is facing the same problem of processes not getting killed [url]

Apache Takes All The Server's Ram With Child Processes

Mar 22, 2008

I do a ps aux, and get a bunch of:

/usr/sbin/httpd

Each one takes up like 4% of the available ram - and when the ram is gone, the server dies (it doesn't have a swap file - half the time you can't even log in to it), and you have to reboot Apache.

I thought of limiting maxchilds, but would that break something else?

Should I just make a swap file? Will that defeat the point of creating child processes?

Long Running Apache Processes In Server-status

I'm not sure I understand the server-status page enough to know if this is a problem or not, but I have several processes that seem to run forever, or until I restart Apache. e.g.

Code:
13-1 21045 0/697/4264 W 59.45 19641 0 0.0 43.28 274.97 66.249.66.133 www.example.com GET /wp/2005/01/ HTTP/1.1
19-1 408 1/834/1831 C 83.52 32463 0 14.8 149.66 263.48 66.249.66.133 www.example.com GET /wp/ HTTP/1.1
30-1 14416 0/430/431 W 35.19 13347 0 0.0 37.42 37.44 66.249.66.133 www.example.com GET /wp/category/issues/ HTTP/1.1

They are almost always on a single domain (there's about 100 on the server) that's a Wordpress site. These processes are also almost always a search engine.

On the rare case I see them running on other domains on the same server they're always on Wordpress sites.

The longer the processes run, the more processor/memory they use, the more they slow the server down.

It seems to have just started in the past few weeks, I've had the site there for a couple years.

Apache :: Number Of Fcgid Processes On Windows Server

Oct 10, 2013

I'm new to fcgid on Windows. my current set up is as follows;

Windows Server 2008
Apache 2.4.4
PHP 5.3.27 (fcgid)
MySQL 5.6.14

1. Looking at windows task manager, each of my processes have 4 threads each. What does this mean?

2. Does the number of FcgidMaxProcesses x memory_limit = Total amount of memory required?

3. Number of Threadsperchild = number of FcgidMaxProcesses ?

I just want to know how these two work together.
