The appear to run under sge, but it runs under to root account (and should be started by root): $ ps -e f -o user,ruser,command … sgeadmin root /usr/sge/bin/lx24-em64t/sge_qmaster > >> Several ulimits can be set in the queue configuration, and can so > >> different for each queue or exechost. > > We don't have any ulimits setting inside queue or other SGE parts, > limits.conf is the only place of the config. > > It is so weird that most of the Compute Nodes pick up the settings correctly, > only a few fail to pick up. Do you log in in by SSH to the node? Then you have to restart the SSH daemon too, as the login process inherits the values the SSH daemon got. The changes of the "nofile" setting should be visible in the shell when you log in too. -- Reuti > Currently, my only workaround is to rebuild the Compute Node (reinstall OS > etc) so that it corrects this issue. > > >> Can you check the limits that are set in the sge_execd and sge_shepherd > processes (/proc/<pid>/limits)? > > I tried to look it up, but I could not find the <pid> directory which is > corresponding to the sgeexecd. > > Cheers, > Derrick > > > On Thu, Jul 4, 2019 at 12:09 AM Skylar Thompson <skyl...@uw.edu> wrote: > Can you check the limits that are set in the sge_execd and sge_shepherd > processes (/proc/<pid>/limits)?
