hmm... there might be something to it. it's a bit hard for me to tell because i have a number of clients that have up- and down-values of multiple gb because i load and share a lot of stuff from a particular community.
but then i also noticed a number of clients that dowloaded 3-4gb from me and gave between 0 and 20mb. i have a feeling that something with these clients is not ok, particularly since i don't recognize most of their nicks.
ok, i just found another thing that looks really suspicious: i have about 100 clients listed who each got at least 2gb from me, but the stats show me a total upload of only 70gb. so there must be something wrong here.
just checked the log and the first message is "Creditfile loaded, 5646 clients are known - Credits expired for 1923 clients!". seems like a large number of purges at startup but i haven't looked at this more systematically.
