I have a web form page the contains an update panel, a timer control and an UpdateProgress control. The timer control contains functions that update several grids, while the UpdateProgress control displays a message telling the user that the page is being updated. The page runs fine for hours and then all of a sudden the UpdateProgress control message just hangs. You have to refresh the page at which time the page acts as expected until the next time it hangs. The timer control c# code includes error processing, which should log any errors to the database, but I get no error messages. At this point I'm lost and wonder if anyone has any suggestion where to look for an answer to what may be causing this problem.
Thanks
