WS-C3750X-48P Switch stack crash.

Hello,

I have a stack of 9x3750X switches and one of them has just crashed. Can anyone tell me what the problem might be?

WS-C3750X-48P Switch stack crash.

Hi Nicos,

Majority of folks on this forum will not have the tools to decode the tracebacks for you, which is necessary to see what caused the crash.

For RCA of this issue, I suggest opening a case with TAC and including the above logs, the crashfiles, and a "show tech".

Like Tinya, I too would suggest such analysis is really something for TAC.  However, as you're running (55)SE1, I would suggest upgrading to (55)SE8.

Hmmmmm ... more than 1 year uptime.  This looks like a memory hog- or memory allocation caused crashed. 

If you have the time to upgrade your 3750 stack, use 12.2(55)SE8.  The current IOS, although slightly stable, is not yet fully "mature".  The "55" IOS started getting stable after the release of 12.2(55)SE5.
