How did you run that command? Have you tried submitting a job script with that command in it to see what you get? > I do not understand where the breakpoint 252/253 comes from, and why it > works with mpiexec directly on the node.

Changing limits.conf won't alter the limits for a running execd or any process it spawns (barring cases where the shepherd spawns an sshd or similar which changes limits via pam_limits. Assuming you are using an init script rather than a systemd unit file to start the daemon you could add explicit invocations to ulimit into /etc/sysconfig/sgeexecd (or other platform dependent file probably something in /etc/defaults for debian derivatives) set the various limits appropriately for the daemon if it doesn't otherwise pick them up. No doubt systemd has some similar mechanism for unit files. William
