Ajax and PageRequestManagerServerErrorException

[Chris Zopers]

Hello,

I have an asp:UpdatePanel with some controls in it.
The UpdatePanel has a Timer as a trigger and a button inside the
UpdatePanel as a trigger.

All works fine, but sometimes I get the following error:

Sys.WebForms.PageRequestManagerServerErrorExceptio n: an unknown error
occurred while processing the request on the server. The status code
returned from the server was: 500

The button updates some records in an Oracle database and the timer gets
some records from the same Oracle database.

I have the impression that the error occurs when the button and the
timer event execute at the same time, but I am not totally sure about
that. Maybe it has something to do with accessing Oracle at the same
time from the same client computer?

Does anyone recognize this exception and knows a solution for this?

Greetings,
Chris

the error means that on the ajax postback, your page is throwing an error.
you shoudl add error logging and error handling to the page.
