Logs are frozen

when i check logs with tail -f /var/log/jitsi/jicofo.log or jvb.log ; they are stuck almost an hour ago and i can not check them…

Meanwhile, when a user leaves the room and comes back; another user in the room is also disconnected and comes with a pop-up Rejoin.

what may be the reason?

I have realized that there is no space because of syslog

why it didn’t handle these logs and what is the way to avoid this?
