Yeah, I was thinking more some internal allocation too.  Thinking back
to when it originally happened, I am wondering if it started when I
added a few new peers. On your box where you see the issue, do you have
many peers configured ?

I also see the problem crop up right away when my external peers go
down. There was a scheduled outage at the IX the other night, so all the
eBGP learned routes were withdrawn. When the eBGP peers came back up
back up, almost none of the routes that were learned from my eBGP peers
were propagated to my iBGP peers.  I had to do a soft clear out on the
peer group for my iBGP peers to see the routes, and even then, it really
is just a subset of what should be sent.  tcpdump confirmed, they were
never pushed out the physical interface.
