When I restart openHAB is OK, But after some hours it begins again.
And when this error is written in the syslog I’m not able to send commands over basicUI (and other UIs).

In the event.log and openhab.log I see nothing related to this problem.

How can I find the source of this error? I have no glue what it is.

  • Platform information:
    • Hardware: RaspberryPi 4
    • OS: Raspbian 5.10.11-v7l+
    • Java Runtime Environment: Zulu11.43+100-CA
    • openHAB version: 3.0.1

Thanks for your help.

#5

Your description is too vague thus barely understandable. Noone wants to help if first thing he has to do is to ask all the details from you, you have to give them upfront.
Do you run openHABian ? If no, how did you install your box ?
How do you start OH ? When did the problem start first ? What did you try so far ?

It’s errors in syslog so it is not an openhab problem itself.
Java is crashing which is always a user’s own problem when he installed it himself.

#6

First I’m no expert, but find clues in the (somewhat obscure) error messages. It appears to me the thread OH-eventexecutor is trying to process a “null” value. Also looking at my system the OH-eventexecutor starts at 1, so it appears whatever is happening is in a loop. I’d check your rules and any other program (or binding) you wrote or run that processes OH events. Also there is a command in the console Shell:threads --list that might help.

That’s all I have.

Thanks for your reply’s.

Do you run openHABian?

No, I use raspbian, because openHABian not work with a SSD-Disk

If no, how did you install your box ?

I install it with APT as is descriped at openHAB on Linux | openHAB

How do you start OH?

I start it with the system start: sudo systemctl enable openhab.service

When did the problem start first?

I’m not sure. My guess its with update to 3.0.1 from 3.0.0. But I’m not sure.

What did you try so far?

Check openhab and event log, but nothing is in there. I removed not used binding, Habbot and Voice.
I also try to find out what is happens when it starts (compare timestamp on syslog wit openhab and event log). And I compare that also with my rules, but find no related event.

It’s errors in syslog so it is not an openhab problem itself.
Java is crashing which is always a user’s own problem when he installed it himself.

Thanks for this hint. I update Zulu java to the latest version and maybe its with that OK. Until now it is OK, but sometimes openHAB runs some days until it happens.

Also there is a command in the console Shell:threads --list that might help

Thanks for this hint. I will check this when it happens again.

#8

That’s not true.

You are possibly suffering from a lack of properly adapting java and OS parameters to OH which is right what openHABian will do for you.
Another major advantage of openHABian is that it provides a well-defined starting point.
In a nutshell, noone knows what you have installed on or done to your box so noone knows where to start debugging so noone or only very few are willing to do this for you.
It is a 1:1 thing and the next individual installation will be different with a different set of problems so there’s little point in spending efforts on this.
Your best choice is to move over.

#9

This is concerning. If you fix that, you might see clues. Might just be a case of looking in the right place.

#10

I’m seeing the same thing. Didn’t happen after the migration to 3 only in the latest sw version. I’m wondering if it can be the rules.

#11

I had the Zulu Azul JDK installed, replaced it for OpenJDK 11 and now the issue seeems to be gone.

#12

After update to the newest Version, it works by me without problems.
My current version is:

openjdk 11.0.10 2021-01-19 LTS
OpenJDK Runtime Environment Zulu11.45+27-CA (build 11.0.10+9-LTS)
OpenJDK Client VM Zulu11.45+27-CA (build 11.0.10+9-LTS, mixed mode)
#13

It not working with update java. After some weeks it happens again.

#14

It happes again. Here the result from Shell:threads --list:
