Disable both nodes - node05 and node07 - in your scheduler.
Submit your job.

When you have time, log into those nodes and look at the system logs
at about the time the failed job starts, and at the mom log.
Are the nodes mounting the users home directory? Are they
authenticating properly - ie are they contacting their NIS or LDAP
ps -eaf --forest   on the nodes - do you see any processes belonging
to this job 2004?
