0781-074 Backend returned warning status for queue

[jlin...@isasa.es]

I've defined a batch queue in my RS/6000 with AIX 4.3.2. Each time I
send a script to this queue I receive the following message, although
the script is correctly processed:

qdaemon: (WARNING): 0781-074 Backend returned warning status for queue
queue1:queue1dev

Could it be due to a bad definition of the script ? How can I test it ?
Note: If I execute the script in the current shell it seems to work
properly.

This is the definition of the queue in /etc/qconfig:

queue1:
device = queue1dev
up = TRUE
queue1dev:
backend = /usr/bin/ksh

Any suggestions would be appreciatte.
Thanks in advance.

It could be the script writes something to stderr, or perhaps exits with a
non-0 exit code that causes this to occur.

delete the queue. qdaemon runs as root. So the backend (ksh) runs as root
too, which in turn runs the scripts someone queues with root permissions!

Hmmm... I don't believe this is the case. The backend (in this case ksh) will
run with the effective user ID of the user that queued the job. To test, I
created a similar queue and created a file /tmp/test with root ownership and
600 permissions. As a non-root user I queued up the a file containing
"/usr/bin/rm /tmp/test" and it doesn't have permission to remove /tmp/test.

^^^^^^^

I think, the script returned an error code that is interpreted as warning
status. The returned error code is the exitcode from the last command.
Maybe an 'exit 0' at the end of the script helps avoiding this error.
