One of the four switches of the stack crashed

[marcin.mucha]

Hi,

I have a question, can You help me?

Symptoms: The switch hangs - after a hard reboot and after two hours switch No. 2 flew out from the stack. After the reboot, everything returned to normal and now when a few days passed switch works without problems.

Devices: WS-C3750X-24T-S

Best regards,

Marcin.

Update IOS. If still happens, contact TAC with crash trace.

12.2(55)SE1???  You're stack is running this?

I'd agree with Paolo.  Upgrade the IOS to 12.2(55)SE4 or 15.0(1)SE2.
