https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276294 --- Comment #3 from O. Hartmann <ohartmann@walstatt.org> --- As of today, the appliance has FreeBSD 14.1-STABLE #2 stable/14-n267607-7e10c2d27a53: Sat May 4 08:33:15 CEST 2024 amd64 The router/FW was up a couple of days/weeks for now. We stopped triggering a restart of mpd5 via cron every night (to force ISP assigning new IPv4/IPv6 at a time it is uncritical for the connection, otherwise the iterruption is performed within business times). I observe that the longer the router/fw runs, the higher the likelyhood that the crash appears after the first "service mpd5 restart" performed after boot. Immediately after boot it takes a couple of attempts to trigger the crash. ------ root@gate:~ # service mpd5 restart Stopping mpd5. Waiting for PIDS: 1076.
