I experience problems with my switch stack of two WS-C3750G-24T-S switches. I had a restart and also from time to time two of the stack ports are down.
I changed the IOS to the latest one and also exchanged the power cords and the stack cables, but the problem still exists.
The only message I get after debugging is this one:
000186: Jun 4 15:59:59: 003143: received msg Ready (10) for sw #02 member
000187: Jun 4 15:59:59: Entering sm_ssm_compare_messages Switch Number 1 Old State 10 New State 10
000188: Jun 4 15:59:59: stack_mgr : during state ready, got event 13(no_master_change) (ignored)

000190: Jun 4 15:59:59: Entering update_sm_record Stack Record: Switch Number: 2 State 4 Real State 10
:Sequence Number: 28 Neighbor FALSE
It is the same every minute, but the ports don't have the same period of failure.
Meanwhile I replaced one of the switches and after that the other with new 3750 switch. In both cases the stack between one old and one new was working well for more than two days. After that when I stack the old switches the stack ports started again to fall from time to time.
