that looks ok to me, no symbols are typically for release assemblies like
system.web.

what you will need to do here is roll up your sleeves and do some debugging.
If you can reproduce the problem, set a break point inside the
application_end event in global asax and let the application start up. If
you do not have code inside the application_end put some immaterial code
like string str = string.empty;

When the break point catches, have a look at the call stack window. It will
tell you which routine called/caused the restart and then you can work from
there. Clicking on the callstack line will take you to the handler causing
the restart.

Be aware though, that after the first break point fires in visual studio.
You will will need to make an immaterial change to the web config file for
the break point to hold again later because studio does some optimization in
the background to prevent the application object from starting again even if
you rebuild the project.
