Is limits.conf actualy relevant to your job launch? It's normally used by pam_limits (on GNU/Linux) which won't necessarily be run. [In the case of SGE, you specify the resource limit as a parameter of the execution daemon (execd), at least with "builtin" remote startup.] I'd verify it by executing something like "procenv -l" under mpirun. (procenv is packaged for the major GNU/Linux distributions.)
