When no munged is running on a host or a node, torque creates an epmty file in
the credentials directory and doesn't close its open fd, which may lead to a
point where the torque process is running out of file descriptors.

The error seems in req_getcred.c line 257+ : I guess there is a
"close(fd);unlink(mungeFileName);" missing.

The bigger Problem ist, that even when munge is disabled on a node (with node
submit allowed) a user can still submit or query:


[zrshj01@n010102 ~]$ qsub -l nodes=1:ppn=24 test.sh
munge: Error: Unable to access "/var/run/munge/munge.socket.2": No such file or
