QueueUnavailableException: "Slow" clients

[manstis]

Hi,

I've noticed if our client takes a long time to start-up (e.g. in DevMode) we receive the below error. Refreshing the browser re-loads the application and the error does not repeat.

Is there something I can do to ensure the client registers it's existence as soon as possible (e.g. in the EntryPoint) or does this suggest I have another problem?

Thanks,

Mike

Have you tried increasing the session timeout in the server? The HTTP session timeout in the servlet container, that is,

[manstis]

Yes, our session timeout is currently as follows however the problem remains:-

  <session-config>

    <session-timeout>180</session-timeout>

  </session-config>

We are experiencing the same issue although the app is running in production and the clients are not particulary slow. The session timeout is set 12 hours.

Any idea on how to fix this?

Thanks & cheers

Did anyone manage to get to the bottom of this problem? I'm experiencing it very frequently since I moved to Errai 3.

Thanks!

Cheers,
