Hi all,
first of all, thanks to the Galaxy Team for this really useful software. Actually I don't really know if my problem is related with Galaxy or with Torque/Maui but I didn't find any solution looking in both Torque and Maui user lists, so I hope that some of you with more experience could give me some good advices. I'm trying to set up Galaxy in a small local virtual environment in order to test it. I started with 2 virtual ubuntu servers called galaxy1 and galaxy2. On galaxy1 I succesfully installed Galaxy, Apache, Torque and Maui. I'm using Postgres ad DBMS. It is installed on another "real" DB server. The virtual server galaxy2 is used as node. Galaxy is working like a charm locally but when I try to use Torque problems arise. Torque alone works correctly. That means that I can submit a job with qsub and everything works. The 2 virtual server (galaxy1 and galaxy2) share a directory (through NFS) in which I installed Galaxy following the "unified method" from the documentation.
Now, as I said, Galaxy alone works, Torque/Maui alone works. When I put the two together nothing works.
As a test I upload (using local runner) a gff file. Then I try to make a filter to the gff using "Filter and sort -> Extract features". When I run this tool the corresponding job on the Torque queue runs forever in Hold state. I report some output from diagnose programs:
The diagnose -j reports the following:

While the showq command reports

The only clear thing to me is that after the submission the scheduler puts it in a Hold state. But I cannot understand why. I also try to run the Galaxy-generated sh script with qsub. Following the Galaxy log:
galaxy.jobs.runners.pbs DEBUG 2011-05-04 04:56:36,748 (27) submitting file /mnt/equallogic1/galaxy/galaxy-dist/database/pbs/27.sh

I copied and run the 27.sh script with the command:
qsub 27.sh
And the job runs correctly. So what it is not clear to me is if the problem is related to Torque/Maui or is related to the way in which the job is submitted from Galaxy.

Sorry for the very long e-mail and thank you very much for any help.
