I=E2=80=99m pretty sure the culprit is my bittorrent client.=20 I suppose I can=20 a) tune my transmission client not to accept so many connections b) tune my kernel to have a bigger listen queue I=E2=80=99m writing here in case someone could point for me the right = sysctl I need to tune for case b) Thanks!
