If your application really is stuck in an infinite loop then you could
just use the profile provider and grab stacks of the application in
question with ustack(). Something like:

profile-997
/execname == "insert-app-name-here"/
{
    @[ustack()] = count();
}

However, you could just use pstack(1) to grab stacks.
