I didn't realize you were talking about Internet connections. Once you
go that route, most of the path quality is outside of your control. My
suggestion only applies where the entire path is inside your own domain.

Have you tried tunneling your database connection through an SSH
session, or a VPN? If that is a more reliable path, it might be worth
the effort to make use of it. As a side effect, it would also hide your
work from both curious and malicious outsiders.

It may just be me, but this sounds like a bug. Have you looked at the
tracker to see if it has already been reported? Since it appears you can
reproduce it reliably, perhaps you should post it there so the
developers can take a closer look at it. If you go that route, I suggest
using Wireshark to capture one or more sessions that lock up the client
and attach the raw capture files onto the bug report. This will help
them identify the actual problem and insure the fix really works.
