Ampbackup.php Got event.. peerstatus

Hello.
I got this in a mail:

Subject: Cron [email protected] /var/lib/asterisk/bin/ampbackup.php 28

Mon, 04 Apr 2011 12:08:02 -0400 - Got event… peerstatus
Mon, 04 Apr 2011 12:08:02 -0400 - No event handler for event ‘peerstatus’

we run ampbackup a few times per day.

Linux Distribution: (Debian 6.0.1)
FreePBX version: (2.8.1)
Asterisk (Ver. 1.6.2.10)

other backups after that worked OK.
