There are lots of stm processes running on the server which is consuming most of the cpu.
Anyone please let us know whats the issue with this? Why so many stm processes are running? How can we remediate this isue?

Re: STM processes consuming most of the CPU
It could be a problem of an older diagnostics version.
What version do you run???
Meanwhile try to restart the diagmond daemon.
Hope this helps!
Regards
Torsten.

restarted the diag. But no luck. Still lots of stm processes are running on the server.

Re: STM processes consuming most of the CPU
Some enterprise monitoring software might be running STM to try and check the health status of the hardware.
I know at least reasonably recent versions of the Hardware Sentry KM for BMC Patrol monitoring system can do this.
My guess would be that whatever process is starting the STM is not getting the answers it's looking for before it times out, leaving an extra process running.
Run "ps -ef |grep stm" and look for stm processes with a parent process ID (PPID) of something other than 1. What is the name of that parent process?

Re: STM processes consuming most of the CPU
(start cstm end exit again, note down the version or use swlist)
Hope this helps!

Re: STM processes consuming most of the CPU
In the mean time I would go ahead and kill those STM processes. Once they are all gone you may be able to troubleshoot what is starting them a little easier.
