Suddenly: KNX shown as online, but no control

Setup, Configuration and Use Beginners

Hi,

I’m running Debian on an Intel NUC with OH 2.5.
My KNX device is a USB-TPUART.

Everything went smoothly for 10 months now.

I’m not aware of any hard- or software changes, but now I realize the following behaviour:

  • I’m not able to control anything through KNX
  • The TPUArt is still shown as online in PaperUI
  • When I reboot the NUC, the behaviour is back to normal
  • At some random time I’ll lose control, again
  • So far I was not able to reproduce that error.

(I’m a Linux noob and usually work through tutorials for each step).

When I launched karaf today, I’ve seen the following errors for the 1st time, could that be related?

Error in initialization script: /var/lib/openhab2/etc/shell.init.script: java.la ng.OutOfMemoryError: unable to create new native thread
Error in initialization s cript: /var/lib/openhab2/etc/scripts/shell.completion.script: java.lang.OutOfMem oryError: unable to create new native thread
Error in initialization script: /var /lib/openhab2/etc/scripts/shell.colors.script: java.lang.OutOfMemoryError: unabl e to create new native thread

This iy my current JAVA Setup

openjdk version "1.8.0_232"
OpenJDK Runtime Environment (Zulu 8.42.0.23-CA-linux64) (build 1.8.0_232-b18)
OpenJDK 64-Bit Server VM (Zulu 8.42.0.23-CA-linux64) (build 25.232-b18, mixed mode)

Any idea where to start?

Thank you!

Do you use the Amazon Echo Control binding ?
Have a look at this thread: Web Socket Error on AmazonEchoControl binding every 65 seconds

OH 2.5.6 contains a fix.

In case you do not want to update your environment single step instructions to update just the one binding are described here: Web Socket Error on AmazonEchoControl binding every 65 seconds
