   Hi Reuti.

   Yes, I can set the limits by hand as root, as you can see below. If
I put the limits of queue to "infinity" and submit a job with request
-l h_vmem=8g, the job run without problems and without limits of
memory.

   Reinstall binaries it is a good idea, but it is a lot of work.
Nevertheless, the test queue is configured only on a node that is
running the 64 bit binaries of sgeexecd and the result is the same. I
guess that No one has this problem, so seems a problem with my
instalation.

     Thank you very much for your help.

     Greetings
