Since updating to current stable syslog-ng, the daemon regularly crashes with SIGABRT, and gets restarted by the supervisor. If running in the foreground with: /usr/sbin/syslog-ng -F --cfgfile /etc/syslog-ng/syslog-ng.conf --control /run/syslog-ng.ctl --persist-file /var/lib/syslog-ng/syslog-ng.persist --pidfile /run/syslog-ng.pid This is stderr: ERROR:lib/window-size-counter.c:76:window_size_counter_sub: assertion failed: (old_value >= value) The same can be observed when stracing the supervised daemon. This happens in both current stable version 3.22.1, and unstable 3.23.1.
