Bus error or shm/shared memory message while running my application

Bjorn Robertsson

I have a problem running my application. Apparently, I am out of 'shared memory'

pytorch error: Unexpected bus error encountered in worker. This might be caused by insufficient shared memory (shm).

The shared memory parameter is applied for the Hardware Tier (HW Tier). You'll need an Domino Admin to change this value.

You can override the shared memory (/dev/shm) limit of 64MB in an execution container to utilize more memory.

Domino version 4.3.1 introduced this as a variable. Older Domino versions cannot change the shared memory settings.
