Hello,

We have developed an AJAX page, which sits within SharePoint. When a user clicks a button, a Web Service call is made via AJAX.

There are 2 SharePoint servers in a load-balanced cluster. When load-balancing is enabled, we see a Javascript alert error message when the button is clicked. This is a sporadic error. However, it occurs very frequently.

The error message is: An error occurred: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed...Details: Error parsing near '<HTML dir="ltr"><H'

We do not see the error when load balancing is disabled.

Has anyone seen this before? Is there a known issue with AJAX load balancing? Can anyone give us a clue as to how to fix this?

Server details are:

Windows Server 2003 R2
MOSS 2007
MOSS 2007 SP1 + WSS v3 SP1
ASP.Net 3.5
Many Thanks

Howard
