Reliable Session problem

Hi,

I know that after 10min without receive data the session is lost, so I have a time from client to send any data(i.e simple `KeepAlive()` method ) to server each 7min.

But, sometime the server show this error :

----------------------------------------
Error Error: 100 : Timestamp: 10/15/2006 9:08:17 PM
Message: HandlingInstanceID: c40e9081-16ba-4982-acf3-061a88d902cf

Does anybody know how to resolve it

Thanks,

Reliable Session problem

  • Oscar Marin

    by default receive timeout value also 10 mins,so session has to live for 10 mins(if you are using default settings)

    Make sure client is not closing the proxy and then trying to reuse same proxy

    if you have client and service on same machine,are you experiencing same problem (just to make sure it is not some network problem)

    please enable WCF verbose trace and trace may provide more info about,who is closing the session.

    if you have repro,please send it to me also,my email id is madhup@microsoft.com

    Hi,

    I found the problem :

    My Service is "PerSession", so if I finish my Client( i.e. serviceproxy.Close() ) after 10min my Service raise the exception on Server...How to finish the reliable session into a normal way

    Response :

    I must create a operation with "Termining=true" and "OneWay=false" (i.e. like a Leave() ), so before finish my Client I call 'serviceproxy.Leave()".

    After it all work fine !!!!!

    Note: I'm using "OneWay=false" because without it sametime I receive a exception about 'faulted state to receive message'. Does WCF receive response(only tcp response) even if the operation is 'OneWay=true' If so, "OneWay=true" can't be used with "Termining=true".

    Am I correct

    Thanks,
    Alexnaldo Santos

    If receivetimeout < reliablesessiontimeout,it may terminate session very early,please change service receivetimeout(receivetimeout > reliablesessiontimeout),This may resolve the problem.

  • vbjunkie

    But before timeout I send data to server... I'm using the default settings for receivetimeout and reliablesessiontimeout. I know that reliablesessiontimeout default is 10min...and receivetimeout
