it shouldn't appear on a regular basis, but there are some cases.  if you
restart the condor_collector for example, you'll see it in the CollectorLog
when the startd sends its next update.

what log are you seeing it in?  also, you can look for that session id
(arsenic:14021:1169759226:477) in the other condor logs to see which daemon is
attempting to resume the invalid session.

you can also increase the debugging level somewhat by modifying the daemon's
debug level in the condor_config file.  an example:


this will cause more detailed info to go into the log file, such as which IP
address and port all the connections are going to and coming from, which should
help us identify what exactly is failing.

it might be a result of daemons restarting, but if not, send your condor logs
(with the increased debug levels) to the condor-admin ticket system.
