panic reboot and log information

denise_7 — Fri, 29 Mar 2002 18:22:44 GMT

Three days ago, we had a server that automatically rebooted,. Up on closer inspection, the log file revealed this message 'reboot after panic: isr.ior= (some number). Has anyone evern seen this error? thanks.

Hi,
Does syslog have any entries pertaining to that error? also, you can go to GSP mode , type sl then e for error logs. this should show more information if any hardware had something to do with the crash.

The isr.ior fault is a data page fault.
isr= interrupt space register
ior= interrupt offset register
So the numbers you see after the ior.isr are the virtual addresses in the memory space.
Take a look in /etc/shutdownlog because most of the time this kind of panic message is logged into that file.

Yes, I have seen it many times.

It means that your server had an event that it couldn't handle and did a transfer of control (TOC)

Do you see a ts99 file in /var/tombstones and/or a crash.# directory under /var/adm/crash?

If you don't have the latter, you can try to create on by executing:

10.2
# savecore -vr

11.0
#savecrash -vr

After that, if you have a service contract, you can call the response center and they willanalyze it for you. 1-800-633-3600

Hope this helps

Hello again,

You may also want to analyze the crash dump (if you have one) by using Q4.

Here are the instructions.

Good luck,

Chris

I had also received the same type of error. Are your servers are Servie Guarded? Actually in the service guarded cond if any of the node doesn't get the heartbeat it happens.

Hi Denise,

Do a q4 analysis of the crash files that get stored in /var/adm/crash. Try this link from itrc on how to do the 14 analysis,
