Hi Chris,
Those values are already set and ready for use. Again, running the
java application alone works well without any issues but adding srun on it
causes the "Shared memory" error.
Thanks,

A quick google implies that it can be related to restrictions on the amount of

This can also affect Open-MPI over IB too:
