Delay in item actions after updateing to openHAB 2.2

  • Platform information:
    • Hardware: Raspberry Pi 3
    • OS: Openhabian
    • openHAB version: 2.2

Hello,

I am running OH2 on a raspberry (OpenHABian) and everything was fine with Version 2.1

After updating to Version 2.2, I realized a high delay of reactions to commands of devices.

If I e.g. turn on a light via a switch in the paper or classic UI, the device needs a long time (5sec up to some minutes!) to react.

Curiously, the reaction time increases the longer the system is running:
After a fresh reboot, everything is fine. After some days, it gets more and more lazy.
I also recognized, the CPU load increases. From 0.2% in average after a fresh boot up to 2% after some days.
The “top” command shows that the openhab process rises up to 120% load where it was around 20% after reboot.

What information is needed to analyse this issue? The normal log files are inconspicuous…

Thanks for your support!
