Script/Rule to Reboot Pi - java.lang.OutOfMemoryError: unable to create native thread

1

Maybe once every other month I get this error below and it basically stops OH from working.

Does anybody have a rule/script that would catch this in the openhab.log and then reboot Pi?

Just run a cron job as root

grep 'java.lang.OutOfMemoryError' /openhab/userdata/logs/openhab.log && reboot

I think, once openhab reboots, it’ll start a new log file so this won’t get re-detected, but do verify this.

But of course you might want to figure out why this happened. Maybe buy a Pi with more RAM?
