Client exit approx 10 seconds after last file synchronized, server drop
connection and exit after timeout (600 seconds).
Same behaviour (same client error) ocurs while I am using ssh transport.
The file at which transfer hangs is diffrent every time, but the error 
is same.

Thanks for help and fix.
