Too many open files #76

Open dominicletz opened 3 years ago

dominicletz commented 3 years ago

On macos a long running diode client eventually shows too many open files errors. In my case ulimit descriptor count is set to 256, but active connections are very low (below 5)

@dominicletz did you close connection properly? There is no timeout in remote/client connection, the connection will hang till remote/client disconnect.

And I tried with client_debug, the connections(socks) were all closed.
