Hi,

The KeepAlive Timeout is set to 2 hours, but we can see that the
connections start terminating after a few minutes.
The KeepAlive module does not seems to be behaving as expected.
The connections are created on port :343.
The configuration file nginx.conf is :-
-------------------------------------------------------------------
user nginx;

error_log /var/log/nginx/error.log info;
