Z2M crashing daily with "ERROR_EXCEEDED_MAXIMUM_ACK_TIMEOUT_COUNT."

[kbonnel]

Over the last few days, my Z2M / SLZB-06M setup is crashing at least once a day. Each time it crashes, the logs report the following:

It will attempt to restart Z2M for a couple of mintues and then just stop.

I am running:

• Home Assistant: 2025.2.1. (though I see a new update this morning)
• Z2M. Current version: 2.1.1-1
• SLZB-06M (running Core 2.7.1) Had a crash with the SMLIGHT 7.4.5 20241127 firmware. Per suggestion in other posts that seemed to be dealing with the same errors (Periodic disconnection of the adapter "ERROR_EXCEEDED_MAXIMUM_ACK_TIMEOUT_COUNT." #23861) I upgraded the zigbee adapter to 8.0.2 yesterday (8.0.2 115200 baud), and still got a crash last night.

This is a test environment, so I am not pulling my hair out yet, just would like to figure out what is causing the crashes.
I am testing the following devices:

• 8 x Third Reality Power Plugs. [3RSP02028BZ] (https://www.zigbee2mqtt.io/devices/3RSP02028BZ.html#third%2520reality-3rsp02028bz). These are very chatty devices, and there is no way to change the reporting schedule, at least per the last forum post I could find on Third Reality's forum. I have reached out to see if they have a beta firmware to test.
• 6 x Sonoff Humidity Sensors: SNZB-02P
• 1 x Aqara Humidity Sensor: WSDCGQ11LM
• 1 x Sonoff ZBDongle-E setup as a Router using factory router firmware.
• 2 x Third Reality Leak Sensors. 3RWS18BZ

Had another crash about an hour ago.

One thing I wanted to check is look at the slzb-06m's log, and this is what I see:
[10:57:20] taskZB | Client limit has been reached!
[10:57:23] taskZB | Client limit has been reached!
...
[10:59:17] taskZB | Client limit has been reached!
[10:59:20] taskZB | Client limit has been reached!
[10:59:23] taskZB | Client limit has been reached!
[10:59:25] taskZB | Client limit has been reached!

As for Z2M, looks like the same error (see below).
