Your best bet would be open a support case (see my signature) and send in the following information:
*output to txt file
dm save 1
dm save 2
***offload following to tftp server
supportsave all <tftp-serv-address> /
You could also try proactively upgrading the code if you are hitting a crash. If you give me your model, I can make a recommendation. With that said, the best bet is to open a case and have our engineers look at the information above.
@acmesupportI wouldn't hold your breath on getting that fixed.
I have been working with support for 12 months on why our 7650's are rebooting, we have it happening at multiple sites, and on single or stacks.
I just updated our switches at one site to 8.0.95g which is the currently recommended firmware, and if it stops at that site, it might stop at the rest of them.
It's generally way to intermittent, and on our switches it says that it was rebooted by 'reload', which as I explained to support we are not rebooting the switches randomly through the day.
