Upgraded system to 2.02 after stable 2.01.

Upgrade appeared to work OK including prompting users to upgrade their
client.

But after a few minutes of running everyone freezes and gets disconnected,
the log shows tons of entries like this -

11:46:39 258 TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=74, Socket=170
11:47:11 240 TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=10, Socket=104
11:47:11 23A TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=2, Socket=126
11:47:11 24A TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=13, Socket=107
11:47:11 23E TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=12, Socket=206

11:47:11 254 TCP *** PHYSICAL PORT DISCONNECTED, Tbl Entry=9, Socket=100

And then moments later -
11:50:27 238 TCP *** NEW PHYS. CONNECTION, Tbl Entry=2, Socket=90
11:50:27 238 TCP *** NEW PHYS. CONNECTION, Tbl Entry=4, Socket=93

11:50:28 238 TCP *** NEW PHYS. CONNECTION, Tbl Entry=10, Socket=101

11:50:29 238 TCP *** NEW PHYS. CONNECTION, Tbl Entry=13, Socket=104

It is bouncing up and down like a yo-yo since upgrade.
