[e-nsp] x450 strange restarts

[Marcin Kuczera]

hello,

we have a lot of old x450-24x switches, but one recently behaves very 
strange.
ExtremeXOS version 12.4.5.3 v1245b3-patch1-6

More complicate, it is x450 in particular location, so replaced by other 
unit - behaves in particular place in the same way:

12/06/2013 17:53:08.52 <Noti:EPM.UnexpctRebootDtect> Slot-1: Booting 
after System Failure.
12/06/2013 17:53:07.23 <Noti:EPM.wd_warm_reset> Slot-1: Changing to 
watchdog warm reset mode

No other information in log, temperature is normal 35.5degrees Celsius.

Any hints ?
Regards,
Marcin
