Public bug reported:

It looks like the parallel collider skips interactions. See attached
script. If you start it with -j1 or set the collider itself in a single-
mode mode, all is fine.

If the script is started in parallel, many particles are going through
the wall. Yes,   there are a lot of warnings like
"InsertionSortCollider.cpp:140 insertionSortParallel: Parallel colliding
failed, starting again in single thread. Consider turning
collider.ompThreads=1 for not wasting CPU time." . But skipping
interactions from my point of view is critical for DEM software.
