Thanks for the example.

We identified the issues we were having in certain environments. Our network infrastructure team here installed a faulty configuration setting patch onto a network load balancer. Causing the notification service to behave erratically while communicating with our client, the entity service appears to have been unaffected.

We will implement the change to the client's configuration.

Thank you for your help,

We did not make the change to the client-side endpoint.

We just turned on the notification without making a explicit configuration of the the endpoint on the client.

Would you be able to provide an example client-side endpoint config for just the notification service?

Just want to quickly check that you also made the timeout change on the client side config?

While waiting for a response we had taken a closer look at http://drc.ideablade.com/xwiki/bin/view/Documentation/code-sample-push-notification and determined that our wsDualHttpBinding on our BOS didn't follow the same pattern so we made our binding look like this.

<wsDualHttpBinding>        <binding name="dualBinding" messageEncoding="Mtom"                 receiveTimeout="00:10:00"                 maxReceivedMessageSize="2147483647"                 maxBufferPoolSize="2147483647">          <reliableSession inactivityTimeout="01:00:00" />          <security mode="None"  />        binding>wsDualHttpBinding>

Which appears to be close to what you are suggesting, but the change didn't work as well.We are only experiencing these errors in a staging environment that is designed to mimic our production environment. This solution appears to be working in development and an intermediary snapshot environment.

I see. In that case, the only other thing I could think of is to try changing the timeouts to a value higher than 00:01:00. For example,

        

You might need to have this set on both the client and server, which means you need to include the serviceModel section onthe client as well. Please let us know whether this works or not.

Thanks for your response DenisK.

However I neglected to mention in my above post that our client is a WPF application

The conclusion reached from the link you send me has do with using a "pollingDuplex" binding which appears to be for silverlight according to the documentation on "http://drc.ideablade.com/xwiki/bin/view/Documentation/code-sample-push-notification". The subsequent link from that post got to a discussion that involves IE8.

Hi JamesM,

There were a couple of posts a while ago from customers that had these similar if not the same errors. Please refer to the link below.

Please let me know if this solves your problem.

We are getting error messages while attempting to subscribe to our BOS's notification service.

In our BOS log on the webserver we are getting this message:

IdeaBlade.EntityModel.Server NotificationServiceManager::AsyncNotify

Removing subscriber after error The message could not be transferred within the allotted timeout of 00:01:00. There was no space available in the reliable channel's transfer window. The time allotted to this operation may have been a portion of a longer timeout.

On the client we are capturing two different exceptions:

IdeaBlade.EntityModel.EntityServerException: The message could not be transferred within the allotted timeout of 00:01:00. There was no space available in the reliable channel's transfer window. The time allotted to this operation may have been a portion of a longer timeout. ---> System.TimeoutException: The message could not be transferred within the allotted timeout of 00:01:00. There was no space available in the reliable channel's transfer window. The time allotted to this operation may have been a portion of a longer timeout.

These errors don't happen all the time, a user may happily use the application with no problems but then later they start to occur and they are instance unspecific.
