I see "supsched" consumes big portion of CPU usage. Does anyone know what the process is about ? OS is HPUX11i. Thanks.

It is the streams scheduler daemon whose value is configurable via the kernel parm NTRSCHED.

The is the uni-processor streams scheduler and all systems have one. Normally this process consumes very few resources but there have been some problems. I would suggest that you search the technical knowledge base and enter "supsched". You will probably find a problem similar to yours.

Keep waiting. There are too many possible causes of your symptoms to list in the Forums. Simply go to the "Search Technical Knowledge Base" and enter "supsched" as a search string and you can then determine which one fits your set of software packages.
Of course, to get to the document you need you need to be under a support agreement --- which is one of the reasons you are under support. You are, aren't you?

Yes. I do have software support. Thanks for reminding me.

I wrote the solution/conclusion here in case somebody runs into the same problem. The problem was caused by a bad patch PHNE_34059. The problem was fixed after this patch had been removed,
