[c-nsp] 3750 Stack Weird 'Failure'

[ChrisSerafin]

I have a stack of 3750's with 4 members, and after an IOS upgarde to 
12.2(50), the stack rebooted and one of the members just keeps 
rebooting, and the logs show the member keeps joining and then getting 
removed from the stack.

I would say this is related to the new IOS, but the reason for the IOS 
upgrade was that it was running a super old version of code, and the 
statck 'was unstable' per the client. So an IOS upgarde was the first 
thing I wanted to try...

So I reboot the stack from the master switch, leave the 'bad' switch 
unplugged for 30 seconds and then plug it in, so that it waits for the 
'bad' member to boot during the master switch stack election process, 
and then all of the switches come up fine......weird.

Anyone heard of this? Crash dump file was found but it was from the old 
version of IOS.

Thanks
