cclogd 99% CPU ?

UNIX HP-UX

Hello,

Can someone tell me why the deamon cclogd use 99% CPU ?
I understand (doing some research on internet) that this deamon is for diagnostic.
here the result of top command and sar commands:
# sar 1 10

I don;t know how to fix it. I didn;t find any core files so I don't know what is the impact if we stop / start diagnostic ...
If someone can give me some advise.

Thanks in advance.
Cheers
Al.

You need to install the latest STM patch for your OS. Or upgrade the OS to a recent version.

Thanks for the quick reply.

I can't upgrade the OS (because of the application to critical and they don't know how to update it so we have to keep the system like this).

If I install the patch what that will require (a reboot ?) if not this will fix the problem ? (but still don't know the cause)

Cheers

The cause is that the guy who wrote cclogd made a boo-boo. You have a broken cclogd. You need the fixed cclogd. That is why you need a patch. Yes, it will probably require a reboot.
