we use Gridengine 6.0u6 on Solaris10/Sparc and are occasionally
getting errors "can't stat ... as stdout_path: Permission denied"
from jobs which are being suspended in subordinate queues.

The setup is the following: we have two queues per host, one for
potentially long running jobs (t) and one for "immediate" jobs (b), with
t being subordinate to b. Thus, when a job in b starts, a job in t 
is being migrated to an other, usually less powerful machine by a 
checkpointing environment attached to t which does a kill -USR1 to 
the job's process group.

All this works usually as it should, but from time to time a job in t
goes into an error state with the above message. The stdout_path
is, of course, owned and writable by the user of the job.
