Can you post more detailed info?

Because this sounds like a network or performance issue, more detailed info about your Server Hardware Spec, Software Config and Testing Environment will be more helpful.

The my apps are used on a intranet network (100Mbps). The server is a dual-xeon,
16 GB RAM. My ZK apps run on JBOSS 4.2.1 patched fon WS.

I can't give you a testing environment because the applications aren't accessible by the internet.

As you can see I'm in a ultra-performant network, so this problems are very strange.

I have to say that all the problems begins with ZKRC1.

And I have also recently seen this exact same infinite "Processing..." problem.

But my environment is ZK 2.4.0 and tomcat 5.5.23.

The problem never occurred when I was hosting tomcat on my own machine but now that I am hosting on a remote VM it happens regularly (but seems random).

While this "Processing..." window is on the screen the server is doing nothing.
CPU and Memory usage are minimal.

Also, a Browser refresh will sometimes cause the little box to pop-up saying "The server is temporarily unavailable" (which is not true because tomcat is still running). And after the refresh is it OK again... until next time.

Any ideas? Or is there some debugging I can enable to help find out what is going on?

Thanks
DM.

Are you using IE?

If so, one of our engineer says he bombed this problem once before, and the scenario is when he is doing IE proxy configuration rapidly.

you can test your WebApps again in other browsers both other machines as client, to see if this problem is still exist.

Also, you can write a filter which need to be declared in web.xml to monitor whats really happened in your Web application's request serving. If the "echo"
of request to response is fine then the problem is in network or client side.


Please take a try and post the result, I'll see what I can help.

No, in my case I saw the "Processing..." problem using Firefox 2.0.0.9.

I have not yet seen the same issue in IE7. Actually IE7 seemed a bit quicker in my case and it appeared as if the responsiveness might be something to do with it. Eg is there some event timeout happening and getting lost.

Can you point me to an example of how to write the web.xml filter you are referring to?

thanks,
DM

Actually i encountered the same problem in my application. I am using zk to implement a simple dashboard. I saw the problem with Firefox/2.0.0.8,firefox/2.0.0.9 and IE 6. I did not try ie 7. After i saw the "processing..." message refressing the page causes "the server is temporarily out of service.Please try again later"
message to pop up. With firefox refreshing the page reloads the page properly,but with ie 6 i have to close and re-open ie6.

Hey,

The same is happening in my application. Tested with FF2+ and IE+6, did not test in IE7.
Could you guys tell what to do in web.xml for more specific information on whats happening?

In my case, i have 5 tabs and 5 nested tabs inside each tab, all with load on demand. But in every content tab there is a new window, so my app has 25 windows, it cross my mind that lots of windows might cause this problem, but I really guessing here...

So guys, please help!

Thanks.

Madruga.

Hello all!

I met the problem many times in ZK's Live Demo, I don't know what to cause this, every time I have to refresh the page.

I visited ZK's Live Demo with IE6.

Hope to resolve it.

Hi Gentleman,

We are starting to look at this issue. In hundreds, if not thousands, of tests, we did observe this phenomenon once (with XP+IE6; none for other combinations), but unable to reproduce it. We will keep trying it. It will be very helpful if someone could identify the pattern. Thanks in advance.

Cheers,
Tom
