Andrew,

That's encouraging to hear that some of the bugs are worked out in the
current CVS version.
I think I'll give that code a try.

Thanks.

of the CVS code for this, and it appears to be stable.  We found the issue
was that the bridge appeared to be running out of ports (this would show up
as a NoFreePortsError showing up in the VenueClient.log file when the client
tries to use the bridge).  This was because the bridge was not indicating
that the port was not in use when it detected the bridge process stopping.
The only difference between this and your problem was that the bridge
continued to show in the list in our case, so this may be a different
problem...
