Process Using High CPU
Sep 4, 2007
I run a dedicated server, Running
CentOS 4.5 final
Apache 2.0.59
php 4.3.11
MySQL 4.1.20
I have a user who has been importing large sql databases and this causes the cpu to run at 80% - 90% this in turn causes high loads and sometimes causing the server to crash.
Is there a way to automatically limit or control how much the process can use or stop the process to allow the server to recover.
Just trying to put some sort of safe guard in place

top output from my server shows a this user was creating a lot of proccesses, even this process has been running for about 30 mins, how can I limit the time a process can stay alive? I suspect it was causing a high load on the server when started.

I have a single mysql process that never stops and running with 10-200% CPU load: URL....
I restart mysql => process coming back
I restart server => process coming back
I kill process => process coming back
I have run:
# mysqladmin -uadmin -p`cat /etc/psa/.psa.shadow` -i 1 processlist
but there was noting that runs >10min.
Code:
> SHOW FULL PROCESSLIST;

| 8110 | admin | localhost | NULL | Query | 0 | init | SHOW FULL PROCESSLIST |
+------+-------+-----------+------+---------+------+-------+-----------------------+
2 rows in set (0.00 sec)
I have strace the PID
Code:
# timeout 1m strace -f -c -p 5873
Process 5873 attached with 30 threads - interrupt to quit
Process 10499 attached (waiting for parent)
Process 10499 resumed (parent 5873 ready)
Process 10502 attached (waiting for parent)
Process 10502 resumed (parent 5873 ready)
Process 10503 attached (waiting for parent)
[code]....
I found with google a hint for high cpu URL....I have deinstalled "health monitor" module, but that was not the reason.I use plesk 12.0.18 Update #38 with CentOS 6.6 (Final).

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)

Mem: 1998 1903 95 0 45 542

I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.

I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.
At this moment for example:
top - 09:00:36 up 15:43, 3 users, load average: 3.57, 4.60, 5.32
Tasks: 144 total, 2 running, 142 sleeping, 0 stopped, 0 zombie

Ive recently installed installed and configured stuff on my new box but after, I realised abnormal memory usage.
Mysql server is taking 256mb, there are somewhere between 6 and 10 apache process taking up at least 40mb each.
Furthermore, when I do: top, I see that the memory usage is increasing by about 120ko each 3 sec.
I am running centos 5.1 and have a load of 0. Basically, there is no one on the server appart from me.
On the server I have at home running debian, I run all thoose thing and it take up 200mb

I'd like to put up here a base question which I hope some will have the goodwill to answer even though it might touch some business secrecies.
We're a gameserver hoster since around ten years, running also vserver products since over two years now. Renting a few Racks in Europe since some time we're a bit in a question mark how rootserver companies deal with the initial hardware costs for every new customer.
Rackspace and today specially power costs are huge cash eaters here in Europe. Dedicated Rootservers are huge space & power consumers per customer ratio. The initial Hw costs for every new rootserver customer might be covered after 4-6 months (if the machine has to be bought newly), adding the bandwidth and power costs it might take up to 8-9 months until a benefit might come in.
Is this the business normality in the rootserver market (waiting 9 months for any benefit, or counting only on the benefit of the 2nd customer using the older Hw), or are the better ways to handle those "initial" costs or keep them affordably low?

My hosting company is telling me that I have getting frozen processes on my VPS that is causing apache to stop responding.
My VPS is CentOS, with 512 megs of memory and my website is a Vbulletin forum. I have several add-ons installed on vbulletin, and if one of those are causing the problem, how do I figure it out?
When http stops responding, I can access the server with putty on ssh. Running the "top" command, it shows that I still have 100+ megs of memory free and the processor is barely being used.
This has happened twice in just 2 - 3 days. This morning, I asked my hosting company what can be causing this, but no answer so far.

I can't remember the name of the utility that lets you watch what a process is doing. You call it on a PID and you can see all the memory allocations, file IO, library loading, etc. that the process is doing as it happens. Anyone know what I'm thinking of?

My dedicated machine (Quad core, 8gb ram running Debian stable latest + Apache2) is giving me a real hard time.
I got a long running php script (a crawler) that takes long to run and keep getting killed.
The code already have max_execution_time set to -1 (also tried 90000) and max_input_time + max_memory set to -1 (meaning no limit).
I run it in shell with nice set to 19 (!) to ensure the OS don't kill it:
>> nice --adjust=19 /usr/bin/php -f crawl.php
And always, at the same time (after 10 mins or so) it get "Killed".
I can't trim down the code as the crawl is dynamic (from link to link).
how I can save the php from getting "killed"?

I'd like a brief explanation of the process of creating a web site.
Once I sign up, how do I actually construct/configure the web site. Are there templates that I change the colours, background and text of? I don't want to actually construct my own web pages. I just want to "brand/personalize" some template and then let it operate. (And if I'm using some ambiguous terms, please correct me.)
Also, I wanted to know if hosting companies allow one to experiment with an "offline" web site; one that I can set up and play with (via a password or such) using their templates until I have a better idea of what I want or what I can do in terms of presentation (perhaps a month?). Once that's done, I wanted the ability to cancel the whole idea or put what I have on line.
To provide some other info:
I am looking for a shared account, and I understand that bandwidth and disk space are the key requirements, but thanks for the reminder. I have heard about some tools, but for the time being let's just talk about process.
