I have none because of the lag with the central node and the missing UPnP option in the client, and conections where limited to 8....
7 Orphans in 5 hours.... really fair coin :/
i always have max of 8 connection. And was mining ok (well i did also get my share of orphans). UPnP IS IN THE CLIENT!!! people, PLEASE stop complaining about the orphans. Especially if you have no idea how solo mining works. how many "invalid" shares do you get on a pool? guess what, those are "orphans"! suck it up!
