Hi,
I have been using OpenHAB for several years successfully and not installed any new version or plugins recently. In the past week, I have been experiencing a lot of different strange problems with my OpenHAB installation, e.g.
- HABPanel not showing all icons and intermediately showing “Trying to connect” errors
- Some rules not being executed anymore
- some items not being updated anymore
while the rest of OpenHAB is still running.
When looking into the logs, I can see a lot of different exceptions there frequently, with different stacktraces, but all showing OutOfMemory errors.
When I execute “free -m” on the machine OpenHAB and HabPanel run on, I see the following memory information:
total used free shared buff/cache available
Mem: 976 797 49 3 130 126
Swap: 99 99 0
I assume this is not a normal memory consumption by OpenHAB, correct?
I can see that the vast majority is used by the java process:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
567 openhab 20 0 2055176 559780 0 S 8.9 56.0 380:38.43 java
I am running OpenHAB version 2.5.1 on a RasperryPi (OpenHABian).
Any ideas how this could be fixed?
Thanks a lot, Torsten
