    I've been getting HTTP 500 errors at random times, and I'm not sure why.  Here are the details:
    • Error message: "Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.  The status code returned from the server was: 500"
    • When debugging the web application on my local machine (VS 2008, .NET 3.5, IE 7), I have never received an error.
    • The error gets raised sporadically on either of our two web servers (Server: W2K3, IIS 6.0; Client: Vista, IE 7), even when there is only 1 active user
    • The error never raises on co-workers' web applications that do not use Telerik, but still use AJAX
    • I cannot tie the error message to any individual Telerik control
    • 2009.2.701.35

    Any help with this would be much appreciated!

    Hello,

    The error Sys.WebForms.PageRequestManagerServerErrorException isn't telerik specific; we get it typically when an error is happening from the server during an AJAX postback.  You will want to look potentially within your code (though it could be telerik-specific); things obviously operate differently when you deal with multiple users or even one user in a remote environment.  Can you post some of the errors you are getting?

    Thanks.

    Brian, thanks for the reply.

    The only error message that I have received is what was posted ("Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.  The status code returned from the server was: 500").  Any thoughts on what may cause this?

    Thanks.
