An error occurred while retrieving Date - Or Http Sessions / Requests Limitation

My issue is in CRM 4.0

My problem was that in forms (edit.aspx) that includes attributes type date, sometimes cause the browser freeze and not responding , after 5 or 6 minutes I gets a global error alert (client - Ok Cancel dialogbox – not modal dialog !!! that Exception Accrued ….) , after hit on OK button I get an alert dialogbox that says "An error occurred while retrieving Date"

I have tried everything, including running the CRMTrace - didn't gets us any ideas …

We getting this exception jest in that cases:All Entities (Custom or not ) with date time (Jest Date Data) attributesAND The value of the date is DAY value <> MONTH value (NOT equal) All cases of date and month that equal like 1/1/yyyy , 2/2/yyyy … there will not be exception and the form will be loaded jest fine.

To make the problem more complicate, I will add the amazing fact that in Browser IE version 7 , this problem not accrued what so ever at all … Please don't respond that all clients should have IE 7 installed – because most of our clients (Intranet) have IE 6 , and I can't change it.

The solution
The solution for my problem, is not about a date format , but it was an issue of limitation of Internet Explorer that limits the number of simultaneous downloads to two downloads, plus one queued download – probably a crm form goes with AJAX to do something with date fields, and that limitation was stop it from working currect.

My solution was to increase that amount by using this :
