Hi Everyone,
I am having problems SSHing from a client to the server. When the server is restarted, everything works fine. Few days/weeks (this happens at irregular intervals) after restarting, the problem (i.e.,not able to SSH) appears again.
note:
-------
I am able to ping the server and get all the replies even when it is not SSH'able. The server which acts as a gateway keeps routing the traffic from the internal network irrespective of the SSH issue.
When I issued an SSH command with the -vvv option, it displays the following:

two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
