    • openHAB version: 3.1.0.M2 - Milestone Build
  • Issue of the topic:
    After some time the CPU load of my openhab instance gets constantly high at 100%
  • I have not much configured, yet. The following bindings are installed with a few thing and items:
    • AVM Fritz
    • CoronaStats
    • Hue Binding
    • MQTT Bniding
    • Pushover Binding
    • Shelly Binding
  • log:
    • Event log contains only info-level events.
    • openhab.log show only one error:
      2021-03-25 18:59:12.139 [ERROR] [.core.model.lsp.internal.ModelServer] - Error starting the Language Server
      java.net.BindException: Address already in use (Bind failed)
      This is caused by my parallel OH2.5 installation, which is already using the port.
      But I will remove the 2nd Language server and retry…
      I guess this shoud not cause any CPU load, does it?

Is there any procedure to identify the root cause of the issue?
