I'm using jsch 0.1.33 to act as a SSH client. Initially everything works fine,
but the client hang almost always hang after running for a weekend. Here's my
scenario:
I have two clients, every hour each client connects to a SSH server, transfer
files, then disconnect. Initially it works fine, but after a couple of days,
one of the clients hang. Here's the stack trace from jdb, it seems to me that
connect blocks at read indefinitely.
main[1] where
[1] java.net.SocketInputStream.socketRead0 (native method)
[2] java.net.SocketInputStream.read (null)
[3] java.net.SocketInputStream.read (null)

Can anybody help? The project is quite urgent, I'll have to solve this problem
soon or else boss will force me to go other routes.
Any input will be appreciated.
