[SOLVED] System slows down, Unknown Error messages

Setup, Configuration and Use Runtime
1

Hi,

my System was running for years very well.
(Running in Pi 3B+ with openhabian)
After updating to latest stable (2.5.1-2) the system slows down dramatically.
After a restart I get a lot of these messages in openhab.log:

[WARN ] [me.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.eclipse.smarthome.core.thing.i
nternal.CommunicationManager@1ae9ddd' takes more than 5000ms.

[WARN] [me.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.eclipse.smarthome.core.internal.items.ItemUpdater@1945e99' takes more than 5000ms.

[WARN ] [me.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.eclipse.smarthome.io.monitor.internal.EventLogger@ae910c' takes more than 5000ms.

[WARN ] [me.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.openhab.core.events.internal.EventBridge@1e57d3f' takes more than 5000ms.

I’ve no idea what’s happening. In the end, the system gets unusable…

Any Idea how to figure out, what causes the issue?

Thanks a lot

You could try stopping OH and clearing the cache & tmp folders. The next start will take longer.
Some people have found that OH needs up to 3 restarts to settle down.

Take a look at your Disk I/O performance.
I observed the same and happened to me, because my SD card was near it’s end… And it was only able to read/write with a few MB/s.

Hi I’m using a SSD no SD Card, so this should not be the problem

I still cleared the cache and I rebooted several times…
Didn’t fixed.
Seems like the system runs well after about 25-30 minutes. Afterwards the erorr messages above occurs and the system slows down

What version did you update from?

7

First I updated from 2.4.0 to 2.5.0 and then to 2.5.1-2

Did it work OK from 2.4.0 to 2.5.0? Invalid addons can cause all addons, including bindings, to reload every minute as the loader tries to load invalid bindings. As documented, a common culprit is restdocs since it moved from misc to ui.
Check your addons.config file in the userdata tree. Stop OH before modifying that file though.

I had this error after upgrading from 2.4.0 to 2.5.0 and I corrected it.
Afterwards it was running well an dthe addons didn’t restarted.
Today I don’t have any log entries that shows up restarting addons

I have not yet updated to 2.5.1 on my production system. Could you post your addons.config here? Perhaps another set of eyes can spot something.

EDIT:
For some reason the forum is posting your messages twice.

sure, here’s the config:

The Reply function isn’t working… that’s why it is posted twice

This config looks fine to me.

Now I frequently get:

Dispatching event to subscriber 'org.eclipse.smarthome.core.interna
l.items.ItemUpdater@19d994e' takes more than 5000ms.

Is it possible to figure out which ITEM/Thing/RULE ist causing it?
What does @19d994e mean?

That is likely an Item, Rule or Event number. You can try turning on debug logging to get more log information.

I just noticed you have exec as a transformation and a binding. I do not know if that is correct. You could try stopping OH, deleting both, start OH, install exec.

Where did you saw this?
What can I do exactly? (Not sure what you mean)
