> I've attempted to stress test the nonblocking server by writing a client
> which connects to said server and executes three operations as fast as
> possible in an infinite loop. I've found that if I kill the client (ctrl +
> C), an intermittent problem occurs where the server will stop accepting new
> connections from clients. In the case of multiple clients already connected,
> they are immediately disconnected.
> I've tracked the bug down to the run method in nonblocking_server.rb,
> specifically the "if fd.handle.eof?" statement (around line 150). Under
> certain conditions executing this line will cause Errno::ECONNRESET to be
> raised. As such, the "@shutdown_queue.push :shutdown" statement is executed,
> which accounts for the behavior I am seeing. The attached patch rescues such
> an error and removes the connection. I am not sure if this is the best way to
> do it, however it solves the problem for me.
