[galaxy-dev] upload files by cluster with pbs-python returns empty files

Hi, We have set up a local instance of galaxy-dist, using pbs-python to communicate with our HPC. Everything is working great, except for the upload functionality. When I assign the upload1 to local:/// , uploading of small files through the web-site works, and upload of large files by ftp works as well. When I let upload1 to be handled by the default_cluster_job_runner ( = pbs:///), I get empty data sets. Galaxy does not report any errors however and the data state is ok. Has anybody seen this issue and solved it? Using the local:/// job handler causes a massive performance hit on the galaxy process. Best regards, Geert Vandeweyer
