A couple of comments about the Win32 client. I'm definitely suspicious 
of it as well. I'm running several Unix clients (Linux FC2), and I have 
no problems with them.

I'm having the exact same problem described above with the 0.09f Win32 
client. It seems to have to do with the size of the stream that's sent 
down to the client from the bbstored server. The server is sending 
directory information to the client, and every time this directory is 
sent, it fails on this client. The size of the stream sent from the 
server to the client before the client disconnects (7/34 on the server) 
is 3744380, which is several orders of magnitude larger than any other 
stream sent by the server.

I run 5 Windows clients, and just one of them is displaying this 
behavior a lot of the time. For 6-8 hour stretches, the client will 
login  over and over again (because of the failure (7/34 on the 
server)), and scan the local disk. Then, suddenly it will work for a 
while (6-72 hours). Note that only one of the 5 clients has this problem.

When the connection works, the object that appears to be the problem is 
not sent from the server, and so things work.

Here is a log snippet (from the server) to illustrate:

Any thoughts would be very welcome.
