Last night, the network was humming along just fine. This morning, It appears that once the network got loaded down somewhat and started doing the freakin' thing again.
Except, this one situation was slightly different than yesterdays. Using EtherApe, the network (from an ip viewpoint) would grow and shrink as would the ability to hit certain machines via tcpip. Segments would join and leave the network at random intervals. EtherApe also allows monitoring at the ethernet level. From that perpective, the network extents were complete and static.. IPX packets could bounce around all regions with no problem or loss.. As far as the machines go, some routers (but not all) would do the low cpu utilization thing, then jump to nearly 100% utilization..and then go back down. We isolated some hardware - just enough for the plant to run; the front office is disconnected except for the servers. The network is stable now (at least the half of it that is still juiced) Weird that it would do that ...All of the dark routers excpet for one had a solid and correct configuration. The one bad apple consistantly misreported status with what was configured. With the bad one dark, the other ones freaked as well (even after cold starts) until their power was extenguished as well.. Waiting on spares ... to tide over until the network is replaced with a new one soon. I'd like to know if anyone else has seen anything remotely like this....
