The value of RESTARTED is set to 2 for a restarted job, but it should be just 1 (or the documentation [man
page] updated of qsub).

from ~/gridengine/source/daemons/qmaster/job_exit.c

      /*
       * case 5: job being rescheduled because it was interrupted and a checkpoint exists
       */
   else if (failed == SSTATE_MIGRATE) {
      DTRACE;
      /* job_restarted == 2 means a checkpoint in the ckpt arena */

Line 1796 states:

               /* userdefined ckpt has always ckpt_interval = 0 */

but also userdefined interfaces can have an interval and a defined signal for a periodically
checkpointing, in whcih case is behaves like the transparent interface (transparent: you must specify a
checkpointing signal; userdefined: specifying a signal is optional).

In line 1813 it's executed anyway:

                  } else if (ckpt_type & CKPT_USER) {

in case it's not zero.

There is already more defined than Hibernator.
