We're using an AdderLink IP VGA+Keyboard<>VNC device which is rather noisy when uncalibrated and therefore continuously updates the screen. Any update at all apparently risks a disconnect, sometimes with automatic reconnect, sometimes resulting in the "Connection Terminated Unknown rectangle encoding 4692 -> exiting" dialog. The numbers vary widely.

CotVNC is significantly slower than e.g. vncviewer when connected to this device, e.g. displaying an initial screen takes 5-5.

Additionally, dragging a dialog with the left mouse button repeatedly causes the following Assertion failure:

2008-09-05 10:41:59.200 Chicken of the VNC[20650:10b] *** Assertion failure in +[QueuedEvent mouseUpEventForButton:location:timestamp:], /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_cotvnc/work/cotvnc/Source/QueuedEvent.m:35
2008-09-05 10:41:59.201 Chicken of the VNC[20650:10b] Invalid parameter not satisfying: buttonNumber >= 1 && buttonNumber <= 3

vncviewer or any other vnc client does not exhibit any of the aforementioned problems.
