(PM) @! Clue to Solution

It finally happenned to me! One of my PM3 ports - #8 - every connection
attempt resulted in a username of @! - I even tried myself and got that
name, and could not connect.

The port goes from @! username, tries to verify password, finally hangs
up, port goes idle, and the next caller gets the same port and the same
result - rebooting solved the problem, but at the expense of "kicking"
out 40 legitimately connected users.

Using ComOS 3.8b17

Just before this port went "wacky" I had an ISDN connection on it -

It so happenned I was helping to debug this user's connection, and got a
snapshot of the PM3 port -

here's the radius accounting log:

As soon as he disconnected, the problems began with @!

Hope this helps someone figure it out!
