This question was posted by a member kwyrick in regular forms and upon searching I couldn't find a reasonable answer so it is a bug. In my daily reports, I have top 10 services. You would think that the top 10 services are generated by some script querying the packet filter database. But I can't find any logs of some of these services in packet filter.
For example in my daily report (screenshot) I have service TCP 50528 and TCP 43135 in top 10. But when I query my logs for the past 2 days, I don't see any hits. Heck I don't have anything in the past week. I can upload my packet filter logs also if needed but I think it can be reproduced easily.
