Hi Evan - I am a bit skeptical that the proposed fix will solve the issue. AFAICS the exception is raised by the server side - and if I read it correctly it happens when the server finds that the socket is already closed when it tries to close it. How could sleeping between 2 process invocation solve this? The port used is an ephemeral port - so it should never be the same?
Does the log show that the same port was being reused?
