You can activate the debugger by sending a break signal over the serial
line. Something like that may happen when you disconnect a serial cable or
switch something off or on that's connected to the serial port.

You can disable the invocation of the debugger with
sysctl -w ddb.fromconsole=0

BTW: When this happens you should be able to get the system back to running
with
ddb> cont

Often you will see some device timeout messages (especially from network
devices) after that wich can be ignored.
