Torque takes preventative measures against prologue and epilogue scripts by placing an alarm around the scripts execution. By default, Torque sets the alarm to go off after 5 minutes of execution. If the script exceeds this time, it will be terminated and the node will be marked down. This timeout can be adjusted by setting the $prologalarm parameter in the mom_priv/config file.
While Torque is executing the epilogue, epilogue.user, or epilogue.precancel scripts, the job will be in the E (exiting) state.
If an epilogue.parallel script cannot open the .OU or .ER files, an error is logged but the script is continued.
