How many transfers per minute does this setup perform? Since you're
using the command-line client, it wont be able to reuse the TCP
connection to the server so it will establish a new one each time. If
you're doing many such requests, you'll eventually put all the
ephemeral ports into a wait state and there won't be any left for new
connections until they timeout. You can try working around this with the
--local-port option, but better would be to re-architect the system to
reuse the proxy connection.
