Home Assistant Crash

[craigwitter]

The problem

When the Zigbee2Mqtt Addon restarts, Home Assistant becomes unresponsive and ultimately is restarted by Supervisor. There are over 170 devices in the integration. I do not notice high CPU usage or memory usage on the VM when the restart is occurring.

What version of Home Assistant Core has the issue?

2025.1.4

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant OS

Integration causing the issue

MQTT

Anything in the logs that might be useful for us?

Additional information

#136495 looks like a similar issue with ZwaveJS (also a lot of devices loading in causing the system to become unresponsive).

I also notice that when the addon starts initially, I can see watchdog timers missed

In further testing, it appears to be related to a template sensor. I disabled this guy:

{% set result = namespace(sensors=[]) %}
{% for state in expand(integration_entities('mqtt') ) | rejectattr('attributes.device_class', 'undefined') | selectattr('attributes.device_class', '==', 'timestamp') %}
{% if 'last_seen' in state.entity_id and (states(state.entity_id) == 'unavailable' or ((as_timestamp(now()) - as_timestamp(states(state.entity_id))) > ((24 | int) * 60 * 60))) %}
{% set result.sensors = result.sensors + [state.name | regex_replace(find=' Last seen', replace='')] %}
{% endif %}
{% endfor %}
{{ result.sensors | join('\n') | truncate(254, True) }}

I can now restart and things don't stop responding
