Hi !
We had the same BGP Problem. But since we turned of PXF (no ip pxf) it
didn't happen again (last 6 weeks).
Cheers,
Chris
P.S. Did see NSE-1 fail after a while ? We already have two replaced, they
started to hang from time to time and after a while wouldn't even boot
anymore.

Hiya,
Just to add to the NSE-1 experience have a look at
CSCds64469
We had a lot of hassle with this bug - any BGP changes occurring on our
network (e.g. if we rebooted an IBGP peer) led to 100% CPU on the NSE-1. We
have a full IBGP mesh with 3 EBGP peers each with a full internet table. The
CPU usage led to peer's closing sessions and major hassles for us.
Recommended IOS from TAC 121-5c.E8 failed to resolve this. As someone
mentioned earlier in this thread it was like the scheduler was broken,
despite the CPU being maxed it wouldn't build peering sessions. We found the
best IOS was actually 12.1(6) main line release. It reported the NSE-1 as
NPE-175 and all of our problems went away!
In the end we pulled out the NSE-1's and we're back to NPE-300's for some
stability.
Cheers
Al
