You will need to do a couple things still.

First is to go to your /etc/pam.d directory and edit one or more of the 
following files (this is based on RedHat EL4 btw so a different dist may 
be different):

rsh (if your using rsh for your remote job dispatch mechanism)
sshd (if your using ssh for your remote job dispatch mechanism)

and add in this line into each of those files:

session    required     pam_limits.so

Some of those files on my RedHat system said certain rules already in 
the file had to be first or last so take note of that if they are there 
for you as well.

Then the next thing is you have to restart the torque daemons on each 
system.  The reason for this is if they were started before you made 
these changes they hold the old limits and all processes they spawn will 
inherit those limits.  So restarting will get Torque going with the 
"unlimited" mode so child processes inherit that.
