using the provided weewx.service on an RPi, ‘sudo systemctl stop weewx’ sends SIGKILL instantly (twice), which is a very unclean termination of weewx and causes me problems. has anyone encountered this and has a proper fix?
so far as i can tell from the manuals (particularly ‘systemd.kill' and ‘systemd.service’), this is defective behaviour by systemd - it should send a SIGTERM followed by a SIGKILL (if necessary) 90 secs later by default. instead, i can only stop it sending SIGKILL by setting ‘FinalKillSignal=SIGTERM’ in weewx.service, where systemd sends SIGTERM twice instead. ‘KillSignal=SIGTERM’ is ignored my workaround is ‘SendSIGKILL=no’ in weewx.service, which nicely sends SIGTERM for clean shutdown, but there is no followup SIGwhatever for contingent termination of rogue process(es) weewx.service with workaround is: # systemd configuration for weewx [Unit] Description=weewx weather system Requires=time-sync.target After=time-sync.target RequiresMountsFor=/home [Service] ExecStart=/home/weewx/bin/weewxd --daemon --pidfile=/run/weewx/weewx.pid /home/weewx/weewx.conf ExecReload=/bin/kill -HUP $MAINPID Type=forking PIDFile=/run/weewx/weewx.pid User=weewx Group=weewx SendSIGKILL=no # workaround to stop SIGKILL sent instantly (systemd bug) [Install] WantedBy=multi-user.target -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
