Is IP routing enabled on that switch?
Best regards,

Hello, thanks for you reply.
No, this Stack doesn´t IP Routing enable.

Fernando,
Did you recently load this IOS?
It seems as this could be memory issue with your 3750. From the message, there should be a crash file written on your flash.
You should open a ticket with TAC and send them the crash file.

Hi Fernando,
Your switch stack crashed then there should be a few "crashinfo" files. Can you post these. I remembered testing this IOS version and I rolled back because I found it was very buggy.

From decoding the crashdump this is a memory corruption crash.
There are two memory corruption crashes that are likely candidates in this IOS image:
CSCta48905 Memory corruption due to ssh
Fixed in 12.2(50)SE3
http://cdetsweb-prd.cisco.com/apps/goto?identifier=CSCsz94252CSCsz94252 Memory Corruption/Crash on reauthenticate on MDA Port with Radius Vlan
Fixed in 12.2(50)SE3 and 12.2(52)SE
It is hard to say from the information available which this event was. The decodes were very generic to memory corruption crashes.
The reason this is common is that in a memory corruption crash the processes that precede the crash are the ones that detect the memory corruption. The process that corrupted the memory will have released control and not be represented in the normal decodes.
In a normal crash that is caused by some code executing the tracebacks will point to those functions and that makes it easier to identify a specific bug.
The simple answer is to upgrade to a current IOS image. As usual when you upgrade you should review the release notes for the new image so you may be aware of any known issues that might impact your network.
