<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Hi All,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We are having an issue at the moment to keep connections alive between the Rabbit Client and Server across 2 different sites with a firewall/load balancer inbetween.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">The Fire wall/Load balancer has an ldle timer of 1 hr after which it closes the underlying tcp connection if the channel is inactive for over an hour.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">This is causing problems especially when the Client has a subscriber listening for messages from a rabbit server behind the firewall.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We added the connFactory.RequestedHeartbeat = 10; and tested this but the connection just seems to close after 10 seconds. It doesn’t seem to work. I don’t know if that’s
something else needs to be enabled ?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">Your help is must appreciated.<o:p></o:p></span></p>
