Connection drops and reconnects

Hello, After recent update (1.7.3), connection to a remote Ubuntu server drops and reconnects after short moment( 1 to 5 minutes).
This connection opens a PostgreSQL tunnel so clients are getting disconnected in the middle of a query.
(Tunnel is stable if opened from shell, in command line: ssh -v -L -g -N user@host)


Hi, I'm sorry about this glitch. Could you please set "Log Level" and paste the log here?
