We are making fun office infrastructure, using raspberrypies. One of them is for music - plain volumio, and other is using mmonit to monitor everything to be up and running.
Monit checks all hosts and services each two minutes, making alerts or other actions if something goes down.
Issue i’ve run into is that every day, around 6:30 (GMT +2) web interface stops repsonding for aroud 5 minutes (or two periods around 2 minutes each).
Meanwhile ICMP requests are passing fine.
My first assumption was that there’s something in cron, but cron is disabled by default in volumio and there were no tasks.
Second thing i’ve found: is logrotate, that’s doing log rotation for nginx daily, but disabling
[ ! -f /var/run/nginx.pid ] || kill -USR1 `cat /var/run/nginx.pid`
didn’t do anything.
This issue is quite annoying (we have sms alerts) , are there any other ideas where to look for it?
