Failed to open a socket

[petere]

I see lots of these in the logs:

[warn] application - Count not connect to partition leader x.x.x.x:9092. Error message: Failed to open a socket.

I can't make anything of that error message. The connection to that host and port should work and succeeds, for example, with netcat.

I think this error is caused by too many tcp connect hasn't been released

That seems to match up with #66 then. I was just surprised that it happened really quickly, whereas I would expect a leak to take a longer time.
