Hello Pete, I wasn't performing the upgrade and the guy who did is not sure whether it was immediate. Anyways he eventually noticed that within an hour or so. Right now it is running smoothly for nearly 23 hours.

What was that time difference compared to when you re-enabled BFD to show TAC and now (assuming it's still stable)?

Yesterday on one of the nodes where no customers are connected yet one colleague of mine noticed some BFD process CPU hogs and some tracebacks and ISIS sessions flapping cause of the BFD flaps. Upgrade to 15.4(1)S1 and reload did not help. What helped was to remove the "isis bfd" from the interface. Strange enough when I added the "isis bfd" back today so that I can see what's going on and to open up the case with cisco nothing happened. So this might be some slow buffer overflow. Has anyone experienced something like this please? adam _______________________________________________ cisco-nsp mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
