How to get the method name where a nil object exception occurs

General
1

I have a stand-alone web application running for one customer that gets nil-object exception errors and I can’t find them. The app.unhandledexception event is getting called and the stack dumped to a text document (see below), but it doesn’t help. Is there something I can do to get the method name?

Thanks,
Bart

UnhandledException: 0

Stack:
RaiseExceptionClass
RaiseNilObjectException
WebSession._WaitingForSync%b%o
WebPushHandler.CheckForChanges%%o
WebPushHandler.!Tickle
_SessionShutdownThread.Event_Run%%o<_SessionShutdownThread>
rbframework.dylib$1100
_pthread_body

You already have it

WebSession._WaitingForSync

But thats internal an not one of your methods
Get your customer to show you how to reproduce it would you ?
Then we can track down whats going on

That’s a tough one. Chances are that it’s a request coming from iOS application requests coming through HandleSpecialURL. This app is running for several customers and this error doesn’t occur every day. I’ll try adding some logging.
