Openhab exited, status=134

After some days running the openhab service crashed.

$ systemctl status openhab
● openhab.service - Starts and stops the openHAB Home Automation Bus
Loaded: loaded (/usr/lib/systemd/system/openhab.service; enabled)

Process: 305 ExecStart=/usr/share/openhab/bin/openhab.sh -o (code=exited, status=134)
Process: 183 ExecStartPre=/usr/share/openhab/bin/setpermissions.sh (code=exited, status=0/SUCCESS)
Main PID: 305 (code=exited, status=134)

I cannot find anything giving me a clue why it crashed in the logs, I checked

  • /var/log/messages
  • /var/log/openhab/openhab.log
  • /var/log/openhab/events.log

This is my running version
$ dpkg -l | grep openhab
ii openhab-addon-binding-exec 1.8.2 all openHAB Exec Binding
ii openhab-addon-persistence-rrd4j 1.8.2 all openHAB RRD4j Persistence
ii openhab-runtime 1.8.2 all openHAB Distribution

Seems solved. I removed the Demo House (including its items, persistence, rules, script, sitemap) and started with my own configuration containing only what I need. No freeze so far. Uptime 8 days.
