Error on shutdown

[Scott Pepperdine]

Hi all,

I have a standalone that loads a stack from an http server.  The 
standalone gets an error on shutdown.  It shows an error that says:
> The instruction at "0x63786520" referenced memory at "0x63786520".  
> The memory could not be "read"

Any suggestions on where I should look for the source of such an error?

Thanks,
--Scott
