Hi,
I'm not sure if it is available on FI, but you can try to make sh tech
end log the output. A part of this output is "dm save" results which can
give overview of warm restart cause. This command exists on XMR/MLX and
is useful in such cases. If you have this command and "dm save" or "sh
tech" shows not correct date:
Created on : 05:00:19 GMT+01 Tue Jul 01 2008
You can try "dm clear" - and wait for another restart. The crash dump is
not overwritten if you don't clear it.

Hi Jeroen,
We have an external syslog server, but nothing shows up except the
Warm restart. I need to take a put a console cable and hope something
shows up screen before crash.
Thanks

But try setting up an external syslog server and see if anything
strange pops up right before the reboot.

Hi Aaron,
Thank you for the info. And that is my gut feeling that its the
management card, but I have been instructed to find a "definitive"
reason for the reboots.
So if someone knows how I can pull any crash info from the fi and
how to analyze it that would be great.

I had this exact issue on a BI about a month ago. It got worse and

until it started rebooting every couple minutes. No reason was
ever found.
I replaced the management card and it hasn't restarted since.

Subject: [f-nsp] debugging restarts
Hi Everyone,
I have another fi that I found has started to restart on its own.
I am getting "Warm start" in the logs that alerted me. I did a
show tech-support but I did not see a reason for the restarts. I
have enabled "debug all" and set "debug destination log" until I
can get a console cable on it and redirect to console.
All power supplies and fans show ok.
Any suggestions on what to check to see why the system is
restarting? I am not seeing anything in the logs or sh commands
that is giving me an idea on what is causing the restarts.
Thanks
Joe
