Hello,
there are newer releases in branch 4.2, was there any reason to stop at
4.2.3?
Back to the backtrace, this one is from shutdown, happening during the
cleanup, not showing the reason of the crash at runtime, unless there
was a manual shut down triggered at that moment. Do you have another
core file?
Cheers,
Daniel
