most likely, you're seeing the effects of aynchronous post-processing of an event: data is recorded when the probe fires, but only post-processed (converting adresses to names, among other things) later. If the process under inspection has gone away by the time post-processing happens, there's nothing to get the names from, and all you see is addresses.
