<div>Morning of the 26th at 9:22 the server was restarted because it

<div>> See the jump from Jul 23rd to Jul 26th. Is this an

No, it just means there was no logger activity for those days. You<br>
need to add a monitoring solution to your Asterisk box (IE: AMI:<br>
Ping).<br>

It's 'well known' that Asterisk gets confused and runs around in a very
tight loop when DNS resolution is failing. Asterisk does a lot of DNS
queries and when the Internet goes down, that puts Asterisk into a
loop. <br>
<br>
Depending on your machine, I am guessing that Asterisk locked up or
dropped out on the 23rd and the restart on the 26th brought it back to
life.<br>
<br>
Nagios is a good choice for monitoring servers and services. I use it
here to monitor all the servers and SIP on my Asterisk box.<br>
