rpcd daemon using 100% of 1 cpu .......why?

[Steven Conkling]

I see this was discussed in other threads, but I never found a reason or answer if this is right or wrong?? Should rpcd be using this much CPU? If not, what can be done to correct it. On a 4 CPU system running HP-UX 11.i rpcd is using almost 100% of 1 cpu. This is the same across at least 3 of my other HP-UX servers.

Apps folks are asking questions about this and I haven't found any answers yet. Any help would be appreciated.

Thanks.............

Are there any errors in /var/opt/dce/svc/*.log? Also check /var/opt/dce/dced/dced.log.

Do you get any output from

# rpccp show mapping

This can happen due to multiple reason (atleast thats what I understand from my research)........two solid reasons I can suggest to have a check are:

1. A network problem. Check your network stats (nestats -an), dns connectivity etc.

2. Some hardware issues (problem in Real Time Clock system caused this bahaviour in few cases).

Use glance to identify what rpcd is actually doing. Check dmesg,syslog for any messages. Use lanadmin, netstat to check the network stats.

Also check for any available patch.

Thanks for all of your suggestions. I ended up using "kill -9" on the parent process "rpcd" which has a defunct child process. None of the stop and starts of Rpcd did anything to stop the process. Although the problem is corrected for now, I still don't understand why it spun out of control on several servers, while others are o.k. I guess I need to open a call with HP to find out if this is a known problem and a patch needs to be applied. But, thanks to all............
