At this point we've lost management access to AGG3 (yet no logs about OSPF neighbor down) and ~half of the active clients behind AGG3 become non-operational. Port-channels from both sides are up and running. I would appreciate any suggestions how to debug and solve the issue.

What mode are you using for your mutichassis etherchannels? From the document below:
Do not use on and off options with PAgP or LACP or Trunk protocol negotiation.
PAgP Run Desirable-Desirable with MEC links.
LACP Run Active-Active with MEC links.
Trunk Run Desirable-Desirable with MEC links.
Hi aleks, did you get the problem solved? We are facing the same problems and I would like to understand what the problem is.
I apologize for the long answer, I was on vacation. Our problem is described here Cisco Bug: CSCvg81219, so we can say that this is not a VSS problem but a problem with с-6880. Since we have no support, we are still looking for a new IOS that can solve this problem (the problem occurs somewhere every three months). What IOS do you use?
we are facing this issue on a WS-C4506-E Switch with SUP v8 installed. Our current IOS version is 152-2.E6. I think I have to open a TAC case for that :-(
Then this problem does not apply the bug indicated in the past message. Of course, if there is support, it is better to go there.
If possible, write what the problem was, thanks.
