I recently installed the updates released by zextras on my mail server and since then the service zmmailboxdctl stops itself and I have to be constantly starting it, I can’t figure out how to fix this problem that’s affecting us considerably.

zextras@:~$ zmcontrol status

memcached Running
mta Running

service webapp Running
service-discover Running

config service Running
zextras@:~$ zmcontrol status
