error: z2m : MQTT error: read ECONNRESET with every shutdown since Zigbee2MQTT 2.0 and Mosquitto Broker 6.5.0

Description of the issue

Every night I do a full system restart of Home Assistant. Triggered by the shutdown, I get the following error messages in the log:
error: z2m : MQTT error: read ECONNRESET

I already had these error messages last year, since October 2024 after updating Zigbee2MQTT to the version 1.40.2-1. See
After the update to Zigbee2MQTT 2.0, these messages were gone. On Tuesday I installed the update for the Mosquitto Broker 6.5.0 and unfortunately these error messages appear again.

I can't say if it's a problem of Zigbee2MQTT, MQTT or the Mosquitto broker. After a bit of research and contributions to similar bugs, the cause seems to have something to do with the fact that after the shutdown command either MQTT or the Broker are terminated faster than Zigbee2MQTT. And Zigbee2MQTT can then no longer access. But that's just a guess.
