When I run the command -
uptime; free -m; mysqladmin processlist
- I get a list of my mysql activity.
There are about 10 sleeping processes for mysql on one of my accounts.
Does anyone know why mysql processes might be sleeping like this?
For the record, there is a very quiet PHPBB forum running on the site in question.
I've found I've got tons of processes "sleeping" on my server, how do I view what processes are sleeping? Is there a command I can run that lists all sleeping (only) processes?

Problem:
Tasks: 580 total, 1 running, 579 sleeping, 0 stopped, 0 zombie
I keep getting too many sleeping processes (300-500) - making the load shoot to 20-50 within 30 minutes.
I stop apache, and restart it in 5 minutes, everythings fine.
Cycle repeats.
Where can I stop this? By editing the httpd.conf file?
Which setting would it be under?
how to kill all mysql processes? Either all in general, or those only with sleep status, or all for a given user.

What are those processes?
anybody here have a review or a way to trace proccess from scratch after top -c or ps -aux
how i got the exact file or user cause this process ....
I just recently switched to using fcgid with cPanel and was wondering how I can go about seeing what is actually running under each process. Before when I was running PHP as CGI I could do psauxwe|grep PID and see all the environmental variables along with the path. I'm not able to do that any longer with fcgid. Is there anyway to get this info now?

Well one of my servers has been under a DDoS attack for a while and I've been doing things to keep it down but there is a suspicious process that keeps running and I am guessing that is whats keeping the server load up because when I stop apache the load goes down but not for long.
The process is this:
Code:
/opt/adobe/fms/fmscore -adaptor _defaultRoot_ -vhost _defaultVHost_ -app registry -inst registry -tag -conf /opt/adobe/fms/conf/Server.xml -name _defaultRoot_:_defaultVHost_:registry:registry:
Does anyone know what this process is or how to block it?
Got some processes that regularly eat up my cpu resources:
%CPU 36.0netstat -plan
%CPU 36.0 /usr/local/apache/bin/httpd -k start -DSSL
%CPU 6.2httpd [truncurl.com] [/leisha?.jpg]
Note leisha.jpg does not even exist!!
%CPU 7.0 /usr/local/bin/python2.4 -S /usr/local/cpanel/3rdparty/mailman/cron/disabled
Something is going seriously wrong with my server,
what can I do ?
My server is frequently down because of kmemsize errors and I'm sure something is misconfigured.
Will try to disable mailman now, pretty strange to find that in my log.

And I just upgraded my Vps to 256mb how does the new spec compare to other 256 vps systems:

On jaguarpc.com, their terms of service state,
"We do not allow programs to run continually in the background. This is to minimize system resources used and operational maintenance needed. We do not allow any chat or topsite programs on our servers other than the ones we pre-install for our clients to use. IRC: We currently DO NOT allow IRC or IRC bots to be operated on our network."
I thought the whole point of using a VPS was so you could run a continuous application (like a chat/game/etc server)? Why are so many VPS services against IRC (the chat server I use is not IRC based, but I just think its wierd so many prohibit IRC)
I'm having a problem with one user account, every 5-10 minutes a spamd process of this user gets locked using 60-90% cpu and never ends. If I don't kill the process another one does the same and they all get locked causing very high loads
I reinstalled exim but it did nothing
The problem persisted even when this user's account was suspended
I'm sure this isn't normal, but I have to ask. Is this normal :
...and if not, why on earth will it be doing this? ....
We have one centos vps, with whm 11 on it. This VPS continuously have following process running and that is eating too much of memory on the server

how to disable this processes, because after killing it, it again starts.
OS: CentOS 5
Software: Apache 2 / PHP CGI 5.8 / suPHP
Today I took the leap and switched to suPHP, rather than the Apache module. This is just what suited us best for hosting our own websites, keeping them more isolated from eachother bar a certain shared directory.
All is great, apart from I'm now noticing Zombie processes all of the time. These processes do seem to go away though, if I watch top the amount of Zombie processes will go up and down between 0 and 10.
Code:
17471 gnation 15 0 0 0 0 Z 1 0.0 0:00.03 php-cgi <defunct>
17463 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct>
17467 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct>
Are these processes a problem, considering they do leave after a while? I've read up about Zombie processes and it would seem that as long as they are closing at some point, instead of hanging around, then that's fine. Is this supposed to happen in my setup?
how can i discover hidden processes running? Already running rkhunter, chrootkit.
[root@kenny ~]# ps auxfww
USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND
Segmentation fault
[root@kenny ~]#
This just appen when i use flag "f = --full". Some running process causing this.
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.
My server has been crashing quite alot lately, it does have some high traffic sites on there but it has never really been this bad before. Today i noticed these in cpanel, what are they and is there anyway I can control them?
View 13 Replies View Relatedi 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]
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?
View 2 Replies View RelatedIs 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.

I've had a shared hosting account for several years and never had this problem before. Since yesterday I occasionally get 500 internal server errors on all my websites simultaneously due to a large number of processes on my account. When I log into cPanel and click on View Processes I only see 1 or 2 at a time, but support tells me that there are actually more than 25 processes and this is not allowed.
Apparently they are defunct PHP processes (zombies?) that are waiting on their 'parent' processes to clean them up and for some reason my account is accumulating a lot of these.
Support is not able to tell me which of my PHP scripts is causing this. All they can give me is something like this:
USERNAME 4541 0.0 0.0 0 0 ? ZN 18:25 0:00 [php] <defunct>
USERNAME 4828 0.0 0.0 0 0 ? ZN 18:25 0:00 [php] <defunct>
USERNAME 5114 0.0 0.0 0 0 ? ZN 18:26 0:00 [php] <defunct>
USERNAME 5265 0.0 0.0 0 0 ? ZN 18:26 0:00 [php] <defunct>
...etc
I have several websites on the account that use my own written PHP. I especially use a lot of functions related to mySQL, simplexml_load_file and reading/writing cache files. I don't know where to start looking to find the PHP that is causing these defunct processes.
To me, this sounds really strange and really unrelated, hopefully it will ring a bell in somebody-who-reads-this' mind...
After enabled suexec in my webserver (litespeed), every day at two regular times, I notice a ton of crond processes on many different users. This slows down my entire server until they go away and it must be resolved.
I have only recently noticed that it is infact crond processes causing this and I hope I have finally found the correct issue. It causes a chain reaction of events and so I have slowly had to crawl up the chain to find the root of the issue... (high iowait, high swapping, high memory, normal processes taking up more cpu%, etc. etc. ........ crond processes)
I have checked every single file in /var/spool/cron and none of the cron jobs run remotely near these times (except some that run every minute/15 minutes for example). Also, I don't understand how so many crond processes could be made at once. I will make a better rough estimate when it next happens.
What could it be causing this to happen?
I was checking my netstat and I saw something like this:

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.
why I have long processes on these two? (time wise)

iowait goes up and down too, along with server loads load average: 2.19, 2.76, 4.31
Do you think I need to change ext3 to ext2?
If so here's my fstab, which bits do I need to change?
LABEL=/ / ext3 defaults,usrquota 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0

/dev/hda2 swap swap defaults 0 0
/usr/tmpDSK /tmp ext3 defaults,noauto 0 0
/tmp /var/tmp ext3 defaults,bind,noauto 0 0
Or should I troubleshoot for something else? If so how/what should I do?
WHM 11.15.0 cPanel 11.18.3-C21703
CENTOS Enterprise 4.6 i686 on standard - WHM X v3.1.0
Few days ago i upgraded cPanel, and then Apache, PHP5, eAccelerator, hadn't updated in ages.
Server worked lightning fast compared to old (PHP 4, older Apache, no eAccelerator), and seemed stable.
Few hours later, server is unresponsive, it took over a day to get the server on the status that i can even see what's happening!
Downgraded back to PHP4, removed suhosin. Still happens. Reworked all the configs, and took all resource limits so low that it survives that, PRM gives 12secs time, enough apache processes etc. Maximum clients lowered to 50 etc. you get the general feel what i did, just to see what's going on.
Now the server survives those 2200+ processes somehow and comes back responsive in some minutes. Killing all PHP processes alone does not solve the problem, but need to restart other services too. All services tend to start crashing when this happens.
Thing is, they are specific user PHP processes, ALL of them, and thus HTTP Request (suPHP), but no log entries for those, i do not see where from they originate, what PHP files are being requested, reworking individual PHP files for that account didn't help at all etc.
I cannot just suspend this account, it's an high importance account for my own needs.
This account gets ~2½million requests a month regularly, and server can handle that.
There was one new reseller account setup for someone else the day this started happening (i upgraded to PHP5 just after accoutn creation) but i think that's unrelated.
Any ideas how to start pursuing a resolution for this? It has started happening more frequently than before, so i'm also suspecting a DDoS, ubt there should be log entries.
Is it possible the requests come so fast that Apache just don't have the time needed to write log?
HDD is the bottleneck actually on this server (ty Leaseweb, you guys gave me the worst HDD of the size you could find and want to charge 25euros a month extra for a proper HDD of same size, 250gb!)
i've noticed a number of times in the past few weeks where the spamd process gets stuck (apache 2 server / whm) with a single user name running the process. there is no spam being sent out, no major incoming influx of mail either - the process is just stuck but consumes 100% of cpu and runs for ages before it terminates itself.
for e.g. right now my top output:
2789 <username> 25 0 99 287:44.76 1.3 79760 49m 2288 R spamd child
the 287 is the cumulative CPU time - no way it should be stuck like this.
how i can figure out what's causing this problem?
