  • Issue of the topic: Openhab crashes

Hello everyone, my Openhab 4.1 system keeps crashing at irregular intervals and then reboots. My system runs on a Raspberry Pi 4 with 8GB RAM. The system was very stable under Openhab 3.x - but since the upgrade to 4.04 and now 4.1, Openhab crashes about 3 to 4 times a week and then restarts. I can’t see much in the log files, except that there seem to be problems writing data to the INflux DB. However, I can’t imagine that this is causing the crash. Can you please help me narrow down the error? I have no idea where to start troubleshooting.

By the way, the INflux DB is running on my Synology NAS, and the Openhab system itself is running on an SSD, which is directly connected to the Raspberry Pi via USB.

So any idea how to identify the problem in my environment?
Many thanks in advance!

Perhaps you could first check if this could be related to running out of memory. But first, does your OS reboot, or is it only openHAB restarting?

You could have a look at this thread: Very High Memory Usage and frequent restarts with OH4 - #10 by laursen

Specifically you could check if you did have OOM:

journalctl -u openhab

And you could verify your memory settings in /etc/default/openhab. I have:

EXTRA_JAVA_OPTS="-Xms192m -Xmx384m -XX:+ExitOnOutOfMemoryError"

which I believe is now also the openHABian default. You could also try to increase both values since you have plenty of memory on your RPi 4 - start out by doubling them, for example.

Thanks for your fast reply! Indeed there is a memory issue as I can see in the output regarding OOM:

I adjusted the EXTRA_JAVA_OPTS values to 384 and 768 and will test the behaviour in the next few days.

I had very high values before (1024 and 2048) and I think this could have caused the problems. I also checked the log file (var/lib/openhab/hs_err_pid1776.log)

Thanks for your help so far! Will update this thread if this solved my problem (decreasing the java heap size).

It is relatively easy to find a good reason. You are using outdated bindings that were built with an old version of the core framework.
If you expect something stable, install only bindings that were built with the 4.1 version of the openHAB core framework.
So, first check the version of all your installed bindings and uninstall all those that are not at version level 4.1.

You are absolutely right! I checked it and deleted old versions (and updated if updated version was available).

Hope that everything is working fine now (as before).
