[GE users] Exploiting backfilling with small s_rt value

Hello,

I've only recently implemented a working resource reservation scheme on our cluster, and I wonder how I can keep users from specifying a small s_rt value, trapping the associated SIGUSR1 signal without properly finishing off the job and with this malevolently exploiting the SGE's backfilling functionality.

Has anyone an idea for a proper workaround to this problem.

I'm grateful for any input!

Best regards,
Sabine
