the session that the execute node has is no longer valid once the collector
restarts.  however, upon seeing this invalid session attempt, the collector
should send notification to the condor_startd on the execute node, and the next
time it sends an update it should start a new session and everything will be
fine.  this notification is done via a UDP packet.

i believe the default update interval is 5 minutes, so if you just wait another
cycle your pool should re-assemble itself.
