MONAI: Unexpected segmentation fault encountered in worker

Describe the bug

when running the unit tests in pytorch 23.03, it sometimes exits into errors:

[2023-04-12T17:08:04.837Z] .ERROR: Unexpected segmentation fault encountered in worker.

[2023-04-12T17:08:05.092Z] ./runtests.sh: line 653:  2477 Segmentation fault      (core dumped) ${cmdPrefix}${cmd} ./tests/runner.py -p "^(?!test_integration).*(?<!_dist)$"

script returned exit code 139

FYI @mingxin-zheng @Nic-Ma, I haven’t found the root cause yet.
