Zigbee2MQTT Stability Issues with Multiple Devices

I’ve been running two Z2M instances with Tasmota Sonoff coordinators for several months now, and everything was working smoothly until recently. My Z2M2 instance, which manages 19 devices, started hanging randomly 3-6 times a day. While my Z2M1 instance, with just 5 devices, remains stable, Z2M2 requires manual or automated restarts, which is quite frustrating. Both instances are up-to-date with the latest HA and Z2M versions, and my coordinators are running the latest firmware. The error logs point to ASH and EmberZNet issues, but I’m not sure how to proceed with troubleshooting. Has anyone else experienced similar problems or have suggestions for resolving this?
