SnoopyPro has a buffer size limitation making it unable to receive
packets above a certain size. If it receives a large packet, it stops
logging. Try this one:

Doesn't have a pretty gui for log analysis, but exports every part of
the packet into a textual log file(SnoopyPros xml output is just useless).
