Hi guys, Since the last upgrade we have observed this error. When submitting a job it sometimes come back failed with the following error tool error An error occurred with this dataset: *Unable to run this job due to a cluster error, please retry it later* * * It is not reproducible as when you relaunch the job it works but still very annoying when demonstrating Galaxy. It looks to me that there is something wrong with torque/pbs and that when one submit a number of jobs, it reaches an internal limit of some kind, and then stops communicating with torque (the batch system). galaxy.jobs DEBUG 2013-09-24 14:05:08,692 (4264) Working directory for job is: /data/galaxyTools/galaxydev/database/job_working_directory/004/4264 galaxy.jobs.handler DEBUG 2013-09-24 14:05:08,700 (4264) Dispatching to pbs runner galaxy.jobs.runners.pbs DEBUG 2013-09-24 14:05:08,885 (4263/9034.galaxy-compute) PBS job state changed from N to R galaxy.jobs DEBUG 2013-09-24 14:05:08,925 (4264) Persisting job destination (destination id: pbs:///) galaxy.jobs.handler INFO 2013-09-24 14:05:09,014 (4264) Job dispatched galaxy.jobs.runners.pbs ERROR 2013-09-24 14:05:09,524 (4262) All attempts to submit job failed galaxy.jobs.runners.pbs DEBUG 2013-09-24 14:05:15,795 (4264) submitting file /data/galaxyTools/galaxydev/database/pbs/4264.sh galaxy.jobs.runners.pbs DEBUG 2013-09-24 14:05:15,795 (4264) command is: python /data/galaxyTools/galaxydev/tools/fastq/fastq_groomer.py '/data/galaxyTools/galaxydev/database/files/007/dataset_7546.dat' 'sanger' '/data/galaxyTools/galaxydev/database/files/007/dataset_7610.dat' 'sanger' 'ascii' 'summarize_input'; cd /data/galaxyTools/galaxydev; /data/galaxyTools/galaxydev/set_metadata.sh ./database/files /data/galaxyTools/galaxydev/database/job_working_directory/004/4264 . /data/galaxyTools/galaxydev/universe_wsgi.ini /data/galaxyTools/galaxydev/database/tmp/tmpcdfNIZ /data/galaxyTools/galaxydev/database/job_working_directory/004/4264/galaxy.json /data/galaxyTools/galaxydev/database/job_working_directory/004/4264/metadata_in_HistoryDatasetAssociation_9064_Zk1kgC,/data/galaxyTools/galaxydev/database/job_working_directory/004/4264/metadata_kwds_HistoryDatasetAssociation_9064_yBjKtV,/data/galaxyTools/galaxydev/database/job_working_directory/004/4264/metadata_out_HistoryDatasetAssociation_9064_RBQTv6,/data/galaxyTools/galaxydev/database/job_working_directory/004/4264/metadata_results_HistoryDatasetAssociation_9064_zBFTMS,,/data/galaxyTools/galaxydev/database/job_working_directory/004/4264/metadata_override_HistoryDatasetAssociation_9064_0W_zYn galaxy.jobs.runners.pbs WARNING 2013-09-24 14:05:15,796 (4264) pbs_submit failed (try 1/5), PBS error 15033: No free connections galaxy.jobs.runners.pbs WARNING 2013-09-24 14:05:17,798 (4264) pbs_submit failed (try 2/5), PBS error 15033: No free connections galaxy.jobs.runners.pbs WARNING 2013-09-24 14:05:19,800 (4264) pbs_submit failed (try 3/5), PBS error 15033: No free connections Did you guys have ever experienced the same problem and if so how did you solve it ?
