hi matthias, i've also been getting metadata errors (below) for several weeks, but it works with the set_metadata_externally option (in the universe config file) set to False. for large files, it could take many minutes for your job server to check the metadata, and no new jobs will be run or completed jobs picked up during this delay, but at least it works reliably. fyi, the time these errors appeared roughly coincided with when i moved the data files (database/) to a different disk than the galaxy code. i don't know for sure if that's the issue or not, but may be a clue; i will experiment when i get a chance. galaxy.datatypes.metadata DEBUG 2011-11-28 12:39:01,129 setting metadata externally failed for Hist oryDatasetAssociation 449: External set_meta() not called galaxy.jobs DEBUG 2011-11-28 12:39:01,221 job 355 ended galaxy.datatypes.metadata DEBUG 2011-11-28 12:39:01,357 Cleaning up external metadata files galaxy.datatypes.metadata DEBUG 2011-11-28 12:39:01,496 Failed to cleanup MetadataTempFile temp fil es from ../../../groupdirs/Galaxy/dev/database/tmp/metadata_out_HistoryDatasetAssociation_449_sB_cT B: No JSON object could be decoded: line 1 column 0 (char 0) On Wed, Nov 16, 2011 at 3:00 AM, Mattias de Hollander < m.dehollander@nioo.knaw.nl> wrote:

** Hello,

I just noticed I get metadata errors in the paster.log file. Can someone tell me what they are and if they are related to above problem?

And of course, how to solve it :)

Any help is appreciated.
