I have two stacks of SGE2000P switches in my building the two stacks are connected by a fiber cable. My main stack 1 keeps going down once a day maybe twice a day for a short amount of time. When I mean down I dont mean they shut off or anything all lights are on and blinking but all the devices on the stack go down for 30 seconds to a minute and a half. There are no logs within the switch saying that anything went down, but my SNMP server shows that the stack went down. For example yesterday it shows it went down from 12:14 AM till 12:15 AM for a total of 31 seconds total. I see stack two go down as well but I cant say its going down for any reason other than stack 1 going down first because that is the traffic path.
I am not sure what to do to try to daignose the problem.
