User Connections from Connection Manager are getting dropped.

Hi OF Team,

It's been couple of days that, my OF server is up and running in my LAN. FYI, we have connection Manager placed in DMZ which will handle requests comming from Internet on port 5222 & will establish a session with my OPENFIRE Server in Lan on port 5262. Today all of a sudden, i heard from some internet users complaining that, spark is getting frequently disconnected.

I tried to check the logs of connection manager, OF server but no clue. Can you please suggest the direction in which i should do troubleshooting.

I am pasting the logs FYR.
