we have been having this issue off and on over the last 6 months. It seems to go through fits. once or twice a month it will go out a single time, but other times it will go out many times a day, or at least once a day. then it will go for weeks with no outages.
there doesn't seem to be any stp traffic. the only thing i see in the event logs is that it registers to switch as disconnected.
For me, it seems that when it becomes really moody, simply reseating doesn't seem to fix it long. i have to power the unit off and let it sit for about 30 minutes. Has anyone found a fix besides spending hundreds/thousands of dollars on such an old system?
thanks
