High Load !!!

[FreeFox]

Hi all,

My server very slowy now and was hung more than 4 time in the day.

When i check the Service Status from WHM appears more than one failed, like apache,cpanel, cppop, eximstats, mysql..etc

And the Server Load larger than 40 and more more .

And when i check it from top command from ssh appear more high load !!

My questions :

* how can i resolve this problem when i see it ?

* how can i kill which cause in the high load ?

Kind Regards

You would need to first have your Server checked, to see if everything is installed and working correctly. Then the focus can be on which processes are running and amounts of Server resources used.

Only then, are you in a good position to determine a fix.

Website Rob,

Thanks for your reply.

Service Status lights are not always accurate. There is a delay in the updating of the same and the check server dameon may need to be restarted.

Checking CPU/Memory/MySQL Usage from WHM may give you an indication what is using the most resources. However it too may nto be updated if the server load is over 5 Perhaps you have a domain on the server with a membership site that is being hit by password traders?

You can also pull up all the process running on the box by using the following from the command line:

ps -aux

The first column will tell you who owns the process. The second column will tell you the process id# (PID). If you see a process using up all the CPU you can run the following from the command line to stop it. Just make sure you know what process you are killing

kill PID#

For more help/options on any command you can type:

man command

man meaning manual and command being the command you want help on. You might also want to consider getting a fully managed server . . .

Hi Freefox,

As suggested by PbG,Please check for the process which is using up the most CPU and memory of the System. Then you can kill the process using the kill command.

ex) kill -9 pid [pid - the process id of the command]

ps command will be helpful to get the process id as well as the cpu and memory usage of individual processess.

ex) ps -auwx | grep <process_name>

Regards,

Bright

if you use redHat enterprise and got the lastest kernel update from RHN got the old one back. The last stock kernels from RHn on system with HT brokes it. Systems starts to get overload since some processes starts to get every idle CPU that appears
