We're looking into this.

One thing that might help would be to also have the master.dag.dagman.log
and master.dag.lib.out files if you still have them.

Also, it would help if you increased the verbosity of the DAGMan output,
and sent the resulting dagman.out file when/if this happens again.

There are two separate verbosity controls (that control different output).
Please do the following:

- Add the setting '-debug 5' on your condor_submit_dag command line.

- Set the configuration macro DAGMAN_DEBUG to D_FULLDEBUG.  You can do
  this in a couple of ways:
    - Put 'DAGMAN_DEBUG = D_FULLDEBUG' into an appropriate configuration
    - Set _CONDOR_DAGMAN_DEBUG to D_FULLDEBUG in your environment before
      running condor_submit_dag.

- You can address number 3 by setting the DAGMAN_NOT_RESPONDING_TIMEOUT
  configuration macro to a value shorter than the default (which is 3600
