> We have developed a component of multi file upload using flex sdk 3 using FileReference Upload built in functionality.
> However we have encountered that the upload fails for more than two files over slow transmission networks.
> On further investigation  We found that the flash is resulting in I/O Errors during the retrieval of total bytes being uploaded for display in the upload progress with the log information as displayed below

> IOError Event : Dispatched when the upload or download fails.[IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2038: File I/O Error. URL: <<http based Post URL>>
> =============================================
> Due to this error the POST request is resulting in Bad Requests on the Web Server because of the missing boundary closures which are required to complete the POST request.
> This issue is always replicable on slow networks which are hovering around 100Kbps
> Request you to look into it and do the needful to provide a fix which needs to be incorporated as one of our customers are critically affected with this functionality miss.
