It looks from the test profile as if we see an OOM during process creation? Memory usage raises from ~4 GB to ~5.26 GB and then abruptly goes back to ~4 GB right after the last test run that is mentioned in the log before the crash. I'd propose to monitor this if it happens again, but I do not see much actionable here. Of course the created process could end for other reasons, too, but we do not have any information from it, AFAICT.
