[galaxy-dev] job cleanup files drmout and drmerr not found

I see following warning messages in galaxy logs after a job finishes up. Does it mean something is misconfigured or a tool did not generate stdout and stderr files? {{{ galaxy.datatypes.metadata DEBUG 2012-01-30 11:52:07,345 loading metadata from file for: HistoryDatasetAssociation 7 galaxy.jobs DEBUG 2012-01-30 11:52:07,743 job 7 ended galaxy.datatypes.metadata DEBUG 2012-01-30 11:52:07,743 Cleaning up external metadata files galaxy.jobs.runners.drmaa WARNING 2012-01-30 11:52:07,806 Unable to cleanup: [Errno 2] No such file or directory: '/scratch/galaxy_personal_install_files/job_working_directory/000/7/7.drmout' galaxy.jobs.runners.drmaa WARNING 2012-01-30 11:52:07,807 Unable to cleanup: [Errno 2] No such file or directory: '/scratch/galaxy_personal_install_files/job_working_directory/000/7/7.drmerr' }}} -- Thanks, Shantanu
