Flex IO error# 2032 when using IE7 for parallel https calls across two servers

Question

Hi,
Weeks back I faced a wierd issue in the behaviour of flashplayer running on IE7 which is invoking parallel https calls. I have two SSL enabled servers one is listening on port 443 and the other is listening on port 8443 but both running in the same domain. I developed a flex client (using httpservice class) which sends parallel https requests to these two servers. When the number of parallel requests increases say more than 5 requests to each server, the fault handler was encountered with the error message:
[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: https://servlet"]. URL: https://servlet"]
I used some http tracer tools to check if the request jumps out of the browser but that didnt happen. I am 100% sure that I am using the correct url. I was totally helpless . This worked without any issues in IE8 or Chrome or Firefox. This made me think about increasing the number of concurrent connections for IE7 by modifying the windows registry. But still no difference in the behaviour.
After breaking my head for a long days, I got one solution which would work. This issue is happening only if we are sending https requests to different ports in the same domain. So rather than moving one among the two servers to a new domain, I got a new DNS name for the same destination. So presently I got two DNS names pointing to the same machine in which both the servers are mounted.
After this it really worked cool!!! Now that I am using a separate DNS name for the server listening on port 8443 and the old DNS name is used to hit the server listening on 443. And I am happy that its working fine without any issues .
But can anyone tell me if this is really an IE7 issue or do we have anyother solution to fix this.
Please share ur thoughts..

Hi,
I am building a mobile employee directory and for that I am using Flash Builder 4.6/AIR 3.1.0. I am using RESTful web service to get XML results and to display on my mobile application. I am getting the same below error when accessing the webservice from mobile app (Android - Galaxy Tab 7 inch).
Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error # 2032"] URL: http://adfdevp.alshaya.com:7013/RESTEmployeeDetails-EmployeeDetails-co">http://adfdevp.alshaya.com:7013/RESTEmployeeDetails-EmployeeDetails-co ntext-root/jersey/restlabhttp://adfdevp.alshaya.com:7013/RESTEmployeeDetails-http://adfdevp.als haya.com:7013/RESTEmployeeDetails-EmployeeDetails-co ntext-root/jersey/restlabEmployeeDetails-context-root/jersey/restlab
The same code is working in Flash Builder 4.6. I have checked Network Monitor to "Disabled" before deploying to mobile. What am i doing wrong here? I am pasting my code below-
