[c-nsp] 6500 having a seizure

[Drew Weaver]

Hey all...

So we've been having issues with this 6500 for awhile now, just doing random stuff so we replaced the chassis and one of the Sups, so today while I was at lunch (doesn't it always happen this way) the switch had one of these:

System returned to ROM by Stateful Switchover (SP by bus error at PC 0x402DF924, address 0x0)

Good times, so after the switch finally "recovered" I noticed this in my log:

.Feb  3 15:47:00.304 EST: %PM-SP-4-PORT_BOUNCED: Port Fa3/48 was bounced by Consistency Check IDBS Down

Since then we replaced the other supervisor which we suspect might be bad, but we're trying to figure out if there is an actual REASON for that:

Feb  3 15:46:59.276 EST: %PM-SP-4-PORT_BOUNCED: Port Fa3/41 was bounced by Consistency Check IDBS Down.

error... We had to go in and shut/no shut interfaces 3/41 - 3/48 manually before the VLANs would come back up...

We would like to avoid any more epilepsy from this box if possible, any ideas?

thanks,
