Hi, I recently upgraded from otrs-5.0.42 to otrs-6.0.28. One weird thing I'm experiencing is that sometimes the daemon process is unstoppable. So when I start the daemon (bin/otrs.Daemon.pl start), I have the following processes: USER PID STAT START COMMAND otrs 31496 SN 11:09 perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31497 SN 11:09 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31498 SN 11:09 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31499 SN 11:09 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31500 SN 11:09 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31501 SN 11:09 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start The amount of children varies but there is ONLY ONE parent (31496). And then suddenly (I haven't yet been able to find the trigger), a new parent arises (32608) and the old parent changes all of its children at once: USER PID STAT START COMMAND otrs 32608 SN 11:15 perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32627 DN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32628 RN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32629 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32630 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 31496 SN 11:09 perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 630 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 631 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 632 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 633 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 634 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start Then if I stop the daemon (bin/otrs.Daemon.pl stop), only the old parent (31496) dies with its children and the new parent (32608) cannot be killed (except with kill -9): USER PID STAT START COMMAND otrs 32608 SN 11:15 perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32627 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32628 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32629 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start otrs 32630 SN 11:15 \_ perl -X /opt/otrs/bin/otrs.Daemon.pl start Any idea what is going on?
