------------------------------
Hi [~lgoldstein],
I would like to provide a brief note on the issue.
There is a client with ssh v2 version (omega) which is connecting to a server
.In order to keep the session alive there is a mechanism from sever to send a
message to client for every 30 seconds so that if there is not packet which
needs to be send from server to client then a message would be sent to client
for every 30 seconds.
The above scenario is able to withstand for one hour and immediately after one
hour even though server sends a message to client ,it is not able to write and
session is becoming idle for 10 mins .
Since ssh default idle timeout is 10 mins ssh server is killing the session.
So we need to understand why exactly after every one hour the message from
server is not written.
It is not that easy for us now to migrate to latest version ,if we can find the
root cause we will try to migrate.
Side effect of this issue is for every two days we are not able to open a new
ssh connection.
connections seems to be in CLOSE_WAIT state and no new connection is
established.
Regards,
Anudeep
