Thanks.
One more thing: the probem also seems to occur on the first (non-ipf) run after
the ipf run. Consecutive runs (unmodified) are OK.

Out of curiosity, if you feel like explaining, how is the inter-particle
collision implemented? It takes lot of time, which is understandable, but it
strikes me as slow even with a very small ipf_distance (if I understand its
purpose correctly). Are you already using some sorting algorithm, like kd-tree
or oct-tree, to optimize things?
