About cclogd daemon

Kenny Chau — Mon, 03 Dec 2001 07:37:55 GMT

I had found that the cclogd daemon had caused the cpu over 90%. Can anyone tell me what had happened to my server and how to view the problem log?

Thanks.

Hi,
It is a known problem.
Yoy need to load a patch PHSS 23658
(. On systems which use the chassis code logging daemon
(cclogd) the daemon will go into an endless loop at
a certain point, and use a high percentage of the CPU.
Such systems include Superdome, N-Class, L-Class,)

A new command called 'cclogview' is available starting
with the March 2001 release of the Online Diagnostics
(Support Tools Manager - STM) for HP-UX servers.

The purpose of the utility is to allow the GSP chassis
logs to be read via the operating system; the output can
be viewed without having access to the console; another
advantage is that tools such as 'vi' and 'grep' can be
used to review the log files.

The GSP logs are logged to the operating system by the
cclogd(1m) daemon, which runs from the operating system.
The files created are cc*log* (such as 'ccbootlog' and 'ccerrlog').
The 'cclogview' utility allows the files to be formatted to viewable
text.

According to the cclogview(1m) man page, this command
will run on all HP-UX systems; however only systems that generate
chassis logs (such as L-class, N-class, Superdome, etc) will
have logs files to view.

Syntax examples:

cclogview /var/stm/logs/os/ccbootlog | more

or

cd /var/stm/logs/os
cclogview ./ccbootlog | more

Thanks for your quick response.

I had got part of the results like this:

Log Entry 1568: 01/01/1970 00:06:26
Alert Level 0: No failure; Keyword: 110F21F
Processor 0 ; Status: 15

0x58e00f001100f21f 0x000046000100061a

So do you know that happened to my server? How to fix it? Need to download the patch for that?

Thanks.
