Warning: no access to tty (Bad file descriptor).

I'm running CentOS, tcshell.

While executing a command that's suppose to distribute jobs to a queue (PBS) I get teh following error:

Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.
/var/spool/pbs/mom_priv/jobs/31607.oscar.SC: line 1: 21956 Killed /home/egs/egsnrc//bin/i686-pc-linux-gnu-g77/dosxyznrc -p 521icru -b -i 0001_exb_test -e /home/egs/egsnrc/ -H /home/egs/egsnrc/ -P 2 -j 1 -f 1

I have no real idea on what it means or how to fix it, been told that it's a tcshell related issue.

This is the command:
exb dosxyznrc [filename] [support file] p=[number of jobs to split]

This is an innocuous warning that simply means you are running a script (rather than a binary) under a job that has no access to the TTY.

In otherwords, you cannot interrupt it (^C), suspend it (^Z) or use other interactive commands because there is no screen or keyboard to interact with it.

It can be safely ignored.
