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.

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.
