The pam_slurm.so<http://pam_slurm.so> module has an impact on these values, if you are using it.

Hello everyone,

I am having the following issue, on the compute nodes “POSIX message queues” is set to unlimited for soft and hard limits.
However, when I do “srun -w node01 --pty bash -I” and then once I am in the node I do “cat /proc/SLURMPID/limits” it shows that “Max msgqueue size” is set to 819200 for both soft and hard limits.
Where is it being set and how do I change it?

Thank you,
