Session Operation Timeout Exception after 'KeyExchangeDhGroupExchangeInit' step

[lchengNetBall]

Hi,

I am using 2016.1.0 version of SSH.NET. Sometime I got "Session Operation Timeout" exception after
"KeyExchangeDhGroupExchangeInit" step.

This is the trace log from debug dll.

Can you please help me out on this issue?

This is a duplicate of #304, which was fixed in 2016.1.0.
