    Random Net connection call failed errors

    aubweb

      Hi All,

       

      I've built a Flex application which is calling coldfusion CFC through remote objects in order to retrieve data.

       

      2 days ago, I've updated the server with coldfusion 9 and my issue is that I have sometime those kind of error messages :

       

      [RPC Fault faultString="error" faultCode="Channel.Call.Failed" faultDetail="NetConnection.Call.Failed: HTTP: Failed"]

       

      [RPC Fault faultString="error" faultCode="Channel.Call.Failed" faultDetail="NetConnection.Call.Failed: HTTP: Status 503"]

       

      [RPC Fault faultString="error" faultCode="Channel.Call.Failed" faultDetail="NetConnection.Call.Failed: HTTP: Status 500"]

       

      [RPC Fault faultString="error" faultCode="Channel.Call.Failed" faultDetail="NetConnection.Call.Failed: HTTP: Status 504"]

       

      [RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'http://servername/flex2gateway/'"]

       

      It was also happening on Coldfusion 8 and even on one other sever with another application.

      (but same logic  Flex -> remote Objects -> CFC -> sql2005).

       

      When we were still running CF8 I added this <add-no-cache-headers>false</add-no-cache-headers> to the service-config.xml file but with no success.

       

      I do not know if it's related to this but I also sometimes have this error message :

      [RPC Fault faultString="Channel disconnected" faultCode="Client.Error.DeliveryInDoubt" faultDetail="Channel disconnected before an acknowledgement was received"]

       

      Most if time the application is running fine, but I want to avoid this errors.

      For example yesterday I recieved +- 50 times the NetConnection.Call.Failed error and 20 times Channel disconnected error.

       

      Do not hesitate to ask if I need to post CF9 settings summary or something else.

       

      Thank you for your help.
