My system (WEBFORMS VB.NET) has presented a null object exception(Object Reference not set to an instance of an Object), which happens only on the production server after an indefinite period of time.
That is to say: After resetting the pool the application goes back to normal, but after some time the exception comes back. And when the error happens ALL the project pages are inaccessible, it is necessary to reset the pool.
- Error does not produce message specifying page or specific line
- It has already been checked and all connections with DB are being closed/opened correctly
- The project has a considerable amount of pages, classes etc.
- The compiler does not charge any variable or Warning for this
Is there any way to get to the root of the error?
has the code that gives this problem?
– novic
So that’s the key point! Nothing has changed in the project. Neither the IDE nor the browser returns a clue as to where the error is, so I don’t know which file the error is in
