Greetings I had an episode again where the data center crashed on me for some reason..

Here is a pastebin of my /var/log/asterisk/messages file..

I decided to ban an IP after looking at the logs however I still don't exactly see what caused the crash..

Here is a few lines before the major crash..

In crontab -e I have this..

*/15 * * * * sh /etc/asterisk/stopez.sh

root@server:/var/log/asterisk# cat /etc/asterisk/stopez.sh
#!/bin/bash
kill -9 $(pgrep ezstream)&
sleep 2s
kill -9 pgrep ezstream
sleep 2s
/usr/sbin/asterisk -rx "module reload"


The above script kills ezstream and reloads the module so far this has worked well for about 6 months now but I do get this periodic crash every 2 or 3 months..
