I’ve tried setting S_DESCRIPTORS, it still cap it at 65535. When running PE jobs, it also multiplies the cores with the max open file value. Even if I set a realistic ulimit, it will hit the threshold with high slots job.

From the above it appears you set the hard limit

Which appears to have been set. Perhaps you could try setting the soft limit
(S_DESCRIPTORS) to whatever value you think appropriate.
