pbs_submit failed, PBS error 15024: Max hop count exceeded
Dear all, I'm not sure if its a galaxy issue, but perhaps someone could give me some advice on where to look or some configuration to set or... I am trying to set up a local installation of Galaxy in for a multi-uer environment. I've installed it on a compute cluster, running centos 5.5, python2.4, a TORQUE scheduler with Maui. Server name: b110-sc-hdn Compute cluster has three nodes. These are called: headnode, computenode1, computenode2 The default queue on the cluster is called "galaxy_queue". I've set jobs to run on this queue in the universe_wsgi.ini file However, when I try to run a job, I get the following error: "galaxy.jobs.runners.pbs DEBUG 2010-11-14 16:48:56,410 (59) pbs_submit failed, PBS error 15024: Max hop count exceeded"
From the research I have done, seemingly this occurs when there are issues resolving the domain name. But, I don't know how to check this or fix this.
I've ran the attached python test script which imports pbs python package. And it works fine. In the script, if I change the server name to "b110-sc-hdn", I recreate the error. Is there something obvious I am not getting? Any help would be very much appreciated and thanks alot for an exceptional tool! Grainne.

Hi Grainne, In your test script, could you see what value pbs.pbs_default() is returning? Also, check that one of the following is true: 'b110-sc-hdn' is set in /etc/hosts and is the same IP address that is resolved by your DNS server? OR 'b110-sc-hdn' does not appear in /etc/hosts, and resolves via DNS to the IP address of your server. --nate
Any help would be very much appreciated and thanks alot for an exceptional tool!

Hi Nate, Thanks a lot for your answer. Embarrasingly, it turns out that it was something obvious I was not getting. I have no excuse as it is pointed out clearly in the wiki - "run Galaxy as a non-root user" - torque does not like jobs to be submitted as root apparently. I've now set up a galaxy user, installed galaxy into the galaxy_user home directory and configured apache's httpd.conf file (all as indicated in the wiki) and it works! Thanks alot, Grainne.
