100% CPU Utilization.

Deeos — Tue, 31 May 2011 13:03:48 GMT

Hi Experts,

I am attaching screenshot of top command where it is showing most of the CPU consuming by httpd process and the same problem we are facing from very long time. Normally, we killed that process when such crisis occurred. But we are still chasing to find root cause behind this issue.

Can it possible to kill the process automatically when it reaches to threshold value?

My system model no.
ia64 hp server rx6600
HP-UX dialapp2 B.11.23 U ia64 1626802519 unlimited-user license

Looking forward for positive response on this!

Regards
Deepak Kumar

Do you know what that httpd is doing now, some cgi script? Try using tusc. Or look at the httpd server logs.
Any child processes:
ps -ef | grep 383

>Can it possible to kill the process automatically when it reaches to threshold value?

You would have to write a script to monitor it.

This should be relatively easy to script, however, you should really be trying figure out the underlying issue. Who is the ceda user. Is this an application, seems like you should be starting there.
