Answer 1

This is an application error caused by what ever is running in the "myApp" folder.

Take a look at whats in there and then come back.

Answer 2

Yes, more info is really needed. On the surface it looks like you have a page that is manipulating a table and it encountered an error that was not handled, so IIS reset the worker process (handled your exception for you). Hwo do you troubleshoot? There are a number of ways, but the one I am most familiar with and use most frequently is to attach the debugger (cdb or windbg), set a BP on the exception that is occuring and then wait. You can then use the debugger to determine the page that is failing and anything more you want. To learn more about this process I'd recommend a book by John Robbins:
