I'm not clear ... did you enable any plugins other than the scanners? Does the same occur if you do a port scan with something like nmap?
Sorry I didn't make that clearer. I was running all plugins allowed by safe checks. In addition, I had disabled all local checks for all OS. I attempted to reproduce the fault with nmap using every scan type. None of the nmap scans resulted in the phones rebooting.
What I've observed in the past is that enabling the global variable setting "Thorough tests" can also cause problems because some service detection plugins will send packets to any port that's flagged as an unknown service, not just those commonly associated with it.
Thorough checks were not enabled.
You could look in the Nessus server log, /opt/nessus/var/nessus/logs/nessusd.messages, provided you have 'log_whole_attack' set to 'yes' in Nessus' config file so that you're logging details of the attack. Alternatively, you might be able to look at the packet capture you have, find when a target stops responding, and see what was being sent before that.
Somehow I knew you were going to say that ;) However, it doesn't hurt to ask for an easy solution before beginning the brain-numbing task of parsing .messages or analyzing packet traces!
