I don't know about gblx, but I saw a problem like this at our border.
After JunOS was upgraded to 5.3r2.4 (other side IOS) the session was
continually being reset.  The bgp session between theser two peers 
was setup with family inet any (for multicast peering) and when that
was removed, the problem went away.  I also heard about a problem that
may be related I2 was having with their Juniper code, it sounded
related, but I haven't investigated the details yet.
