You could be hitting your servers' (IIS, Apache) maximum number of connections 
- which means your application (and thus your custom logs) wouldn't even be 
run.  The server would just eat the requests and send back a 500 level HTTP 
response.

Check your servers' error logs, and see if anything appears in there.

Subject: [flexcoders] What are the chances Flex could be causing this?


Hi, we've got a webservice with about 10 methods. When the application starts 
up it calls about 6 of them in quick succession (I'm currently chaining those 
calls).

If I upload the SWF to our dev environment, create a tab-group in IE (10 tabs 
in total), with each tab loading the swf, I can load 10 instances of the 
application similtaneously.
When I do that I'm seeing that several instances of the app are throwing errors 
like this:

18:06:08.273 | [ERROR] | mx.messaging.Producer | 
'B8ED2C1F-ABBE-DB29-3DB4-1AC289775CF2' producer fault for 
'F87115A3-7C5D-2F13-2EA0-1AC2ED13E733'.18:06:08.304 | [ERROR] | 
Tools.business.AbstractRPCConsumer.fault | faultCode:Server.Error.Request 
faultString:'HTTP request error' faultDetail:'Error: [IOErrorEvent 
type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: 
Stream Error. URL: http://dev- ........

I'm pretty sure this is a server-side issue but want to make absolutely sure. 
The server logs in place don't show any errors  (but I'm just a front-end guy 
looking at some custom error logs - I could easily be missing something!) - 
many of the Flex calls are getting rejected.

Or could this be a red herring? Perhaps the browser is imposing a limits on the 
number of connections opened and I can't test things this way.  If anyone has 
thoughts on whether I could be doing anything weird on the front-end to cause 
this please let me know.

Thanks.
