Sandbox Error Violation issue connecting from Flash Builder

Question

I am trying to walk through the Getting started tutorials on the adobe developer site. I am using Flash Builder and I created a Flex 4 project. Other than that I pretty much followed the tutorial steps. In the debugger I am getting the following. Anyone figure out how to fix this. I have tried adding a crossdomain.xml to the webroot of the blazeds server. Does not seam to help.
Warning: Timeout on xmlsocket://localhost:27813 (at 3 seconds) while waiting for socket policy file.  This should not cause any problems, but see http://www.adobe.com/go/strict_policy_files for an explanation.
Error: SWF from http://localhost:8400/samples/blaze-tutorial-debug/main.swf may not connect to a socket in its own domain without a policy file.  See http://www.adobe.com/go/strict_policy_files to fix this problem.
*** Security Sandbox Violation ***
Connection to localhost:27813 halted - not permitted from http://localhost:8400/samples/blaze-tutorial-debug/main.swf

Hi. Did you try asking about this problem on the FlashBuilder forum? I don't think this is related to BlazeDS.
BlazeDS wouldn't be trying to connect to a local socket. Also, adding a crossdomain.xml file to the BlazeDS server wouldn't help with this as the player is not trying to connect to the BlazeDS server but to a local socket.
Is the NetworkMonitor in FlashBuilder running? If I had to make a guess, I would say that maybe the NetworkMonitor is listening on that port and the player is trying to connect to the network monitor.
You might need to do something in FlashBuilder to allow the player to connect to the socket. Someone on the FlashBuilder forum should be able to help you.
