----------------------------------
Thanks [~lgoldstein] no progress. From the client side, I have increased
the time out to 10 secs. But still no progres.. After 10 secs, client gets the
error saying connection reset. On the SFTP Server side, I see few ports are
in ESTABLISHED state, and when I checked the logs for that port, I see this.
some more inputs. on client side, all connections are closed. But Server side,
few ports are still in ESTABLISHED state. I took one port and looked into the
server logs. here is the output

> Project: MINA SSHD
> Issue Type: Question
> Reporter: Sreedhar J
> Priority: Major
>
> as part of my performance test, I am sending 180 concurrent requests to
> Apache SFTP Server, but I can got the test completed. around 10 to 15
> requests gets timed out. Are there any known tuning properties on the
> SSHD/SFTP Server which increases the concurrent connecttion request
> processing.
> Also, Anyone has some data around max concurrent connections?
