Symptoms

1. In Argus Affiliate, create a Local Event with many data elements, for example:
    2 Relevant History
    2 Lab Data
    2 Reporter Information
    2 Product
    2 Event
    1 Contact
    1 Attachment
2. Route the Local Event to Central
3. Navigate to Argus Safety > Local Affiliate > Incoming Review and query for the Local Event
4. Select Accept Local Event
5. In the Affiliate Acceptance webpage dialog, check Import for all data elements and click on Accept Initial (or Accept Followup)
6. Receive an Internet Explorer Script Error:

    Sys.Webforms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.    
    The status code returned from the server was: 500
    URL: https//<machine_name>.<domain>/ArgusNET/LAM/InitialFollowupAcceptance.aspx ...

7. The http trace file (obtained using Doc ID 1037979.1) contains:

    [InvalidOperationException: Operation is not valid due to the current state of the object.]
       System.Web.HttpValueCollection.ThrowIfMaxHttpCollectionKeysExceeded() +2692302

This occurs every time for all users, but only for specific cases / follow ups which contain a lot of data elements.
