Asterisk restart during voicemail activity

I have an issue with dropped calls periodically, all active calls. It appears that the asterisk process is restarting after voicemail activity. The first entry in the /var/log/asterisk/full after a restart is “Parsing ‘/etc/asterisk/logger.conf’” So I parsed the existing 8 full logs for that string and captured the two previous lines before the reboot. It appears that the asterisk process restarts during voicemail activity.

The server is a new (Oct 2011) dell 310 that has been working fine up til about a month ago.

[[email protected] asterisk]# cat /etc/asterisk/freepbxdistro-version
1.8.2.0-2

Asterisk 1.8.7.1 currently running on pbx (pid = 12575)

Here is the grep of the full log files
