Hello Paul, is it possible to install the package systemd-coredump on the systems showing this crash? Then after the next crash in the output of 'journalctl --no-pager' should the segfault appear followed by a backtrace that you could forward to this bug. This should clarify which function calls lead to the crash. More information on improving that information additionally are here: https://wiki.debian.org/HowToGetABacktrace Kind regards, Bernhard
