[Condor-users] 6.8.0 DAGMan assertion causing hold?

["Michael S. Root" <mike@xxxxxxxxxxxxxx>]

Hi.  I'm seeing a behavior in DAGMan in 6.8.0 that I never saw in 6.6.10 
(our previously installed version).  Every once in a while, a DAG will 
get put on hold automatically, for no apparent reason.  After some 
digging in the logs, I see this in the DAG's dagman.out log:

   9/6 12:37:41 BAD EVENT: job (4952.0.0) ended, submit count < 1 (0)
   9/6 12:37:41 BAD EVENT is warning only
   9/6 12:37:41 ERROR "Assertion ERROR on (job->_queuedNodeJobProcs >= 
0)" at line 608 in file dag.C

And this in the submit machine's SchedLog:

   9/6 12:37:41 (pid:14159) (4561.0) Problem parsing user policy for 
job: The UNKNOWN (never set) OnExitRemove expression '' evaluated to 
UNDEFINED.  Putting job on hold.
   9/6 12:37:41 (pid:14159) Job 4561.0 put on hold: The UNKNOWN (never 
set) OnExitRemove expression '' evaluated to UNDEFINED

When the DAG job is released, it seems to continue on just fine.  Is 
this a bug in 6.8.0?  I can send complete logs for the DAG and the 
submit machine to a developer (~400k) if that'd be helpful.
