Log and db flooded by "Task exception was never retrieved"

The problem

The log and db is being flooded repetitively by the same error "Error doing job: Task exception was never retrieved" every 2-10ms, resulting in rapidly increasing disk and CPU usages. It seems to occur if using a non defined variable of a trigger event.

Below is an example of the number of occurrences in less than one minut.

Logger: homeassistant Source: helpers/template.py:686 First occurred: 09:23:26 (14479 occurrences) Last logged: 09:24:22

The behavior is triggered by many of my automation, which I never have had issues with before. The automation below is just one of them.

What version of Home Assistant Core has the issue?

core-2024.2.1

What was the last working version of Home Assistant Core?

core-2024.1.6

What type of installation are you running?

Home Assistant OS

This has been reported on community forums too:

• https://community.home-assistant.io/t/assertionerror-in-an-automation-with-state-change-trigger/689140
• https://community.home-assistant.io/t/getting-the-same-error-every-100ms-on-2024-2-1-and-cannot-locate-cause/688349

The consensus is it looks to be caused by state_changed trigger, in a condition which refers to trigger.

This is a regression introduced in 2024.2.1, and worked in 2024.1.6. It results in wearing off disk (when logged) and high cpu usage.

Any updates on this? I had to rollback to 2024.1.6 from 2024.2.1, and not sure if it’s safe to try updating again atm.

I have the same problem. Are there any info, what to do? Pls!

I silenced the log message in configuration.yaml using logger section:

logger:
  filters:
    # https://github.com/home-assistant/core/issues/110456
    homeassistant:
      - "Error doing job: Task exception was never retrieved"

Is it great? No. But I don't know how to attract the right attention to this issue, and this saves my ODROID eMMC, which is not replaceable.

Same issue? Thanks for the tip about silencing the logger, wonder if that'll help me...

I think this is caused by the

          - condition: template
            value_template: >-
              {{trigger.from_state.state|float*1.05<trigger.to_state.state|float}}

But now I am wondering, you have 4 triggers (from which 1 is disabled). The template you use seems to expect a certain trigger to have happened, could that be the case?

I think that template is indeed the cause, as those variables will only exist on certain triggers, but not on the timer trigger. So I expect this will occur when the timer finishes.

However, it should not cause this many logs

Right so we dove a bit into this and there might be an issue with async code. We can't replicate this ourselves on our system so we are suspecting this is caused by a custom component. Can you reboot in safe mode and check if this still exists?

Given I’m experiencing the same from a template condition which isn’t properly handling errors itself, would it help to have a list of my custom components?

I am not going to dive into every custom component at this moment. I first want to check if that is actually the reason why this happens.

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

The AssertionError should normally not be reachable, which indicates you have an integration doing non-threadsafe operations on asyncio objects which is corrupting the internal asyncio state.

When an integration modifies the event loop internals from another thread the behavior is undefined and will usually eventually lead to a crash.

If you put asyncio in debug mode, it will be able to detect some of these bad calls and maybe even block them. You can use the profiler service to do that: https://www.home-assistant.io/integrations/profiler/#service-profilerset_asyncio_debug

If you can't get far enough along you can also enable debugpy: in configuration.yaml instead (but its much slower) https://www.home-assistant.io/integrations/debugpy/
