Mosquitto broker terminating and starting about every minute?

Setup, Configuration and Use Installation

I’m wondering anyone has seen this before. My mosquitto broker seems to go offline about every minute or so, for no apparent reason, it terminates and then starts again, clients are disconnected, and they reconnect. not sure what the deal is.

if I stop mosquitto and start with in verbose mode “mosquitto -v” this behavior seems to stop. but anytime mosquitto is starts on reboot with systemctl I get this behavior. any thoughts on this?
thanks much++

What OH version are you using?

Try stopping OH, cleaning the cache and after OH fully restarts do two more restarts of OH.

sudo systemctl stop openhab2

sudo openhab-cli clean-cache

sudo systemctl start openhab2

sudo systemctl restart openhab2

I’m not using the OH MQTT binding, it’s a mosquitto installation independent of my OH installation.

Mosquitto was not creating a mosquitto.pid file on startup for some odd reason. not sure if it’s the best way to go about it, but added:

ExecStartPost=/bin/sh -c ‘umask 022; pgrep mosquitto > /var/run/mosquitto.pid’

to my systemd startup file and it’s working fine now.
