Default ulimit setting in torque overide ulimit setting

Even though you may have setup the ulimit correctly as suggested by Blog entry "Checking that the ulimit is correct when login as ssh", your job may still encounter the error is you are using torque resource manager.
This is because the default setting in /etc/init.d/pbs_mom is set too low and overide the ulimit setting, the default setting at /etc/init.d/pbs_mom should be changed to

ulimit -l unlimited
ulimit -c unlimited
ulimit -n 32768
#ulimit -n 20000
#ulimit -i 20000
