[c-nsp] IPv6 tblver incrementing quickly on RSP720-3CXL

Hi Folks,

I've got a 7609 with a RSP720-3CXL-GE running Version 15.4(3)S6.

IPv6 BGP is sending far too many updates to iBGP neighbors and downstream
customers getting a full BGP feed.

After running 6 days, the tblver is up to 133 million, and 61 million
updates have been sent to full-feed peers. From "sh bgp ipv6 uni sum".

It looks like every 2 - 10 minutes, the entire v6 BGP table is
re-evaluated, resulting in BGP UPDATE messages for every prefix in the RIB
to be sent to peers.

I can't see any trigger event in logs.

Any suggestions about what's going on?  Am I hitting a bug?
