Hi,

It appears that you have memory issues with one of the 3750s.  I you have upgraded the IOS recently, revert back to the old one and see if the problems goes away, if not, try a different IOS version.  Also open a ticket with TAC and send them the crash file.

12.2(58)SE

Stay away from the version "0".  Upgrade to 12.2(58)SE2 instead.

Hellow everyone.

What have I done.

Make backup config.

Make out the stack.

1. Upgrade ios to 12.2(58)SE2.

2. Delete all config on flash, flash2, flash3, flash4 exept ios.

3. Write erase.

4. Reload.

5. Make the stack.

6. Restore the configuration.

All is fine now.

Th's for advise.
