Exactly what I was about to say - get upgrading. I'm running 15.0(2)SG9
I believe, and it's been wonderfully stable for me. There are a lot of
'nice' improvements in 15.x with regards to BGP (i.e. Enhanced Refresh,
Graceful Restart).

There is an odd bug in there with regards to IPv6 access-classes for
VTYs however; doing anything other than 'deny any any' by itself in the
ACL, will permit anything.

I've not submitted it as these are EoS now and I don't fancy wasting my
time, though perhaps SG10/11 fixed it - test well. :)
