I have a problem with dagman and jobs in it, which are queued >1. Then the dagman fails, but the jobs will be submitted.
Dagman with job queued 1 work fine, there are no problems.
One limitation exists: each Condor submit description file must submit only one job. There may not be multiple queue commands, or DAGMan will fail. This requirement exists to enforce the requirements of a well-defined DAG. If each node of the DAG could cause the submission of multiple Condor jobs, then it would violate the definition of a DAG.
