I encountered a similar issue with httperf nearly 1 month ago. I may be wrong for your case but I think it's due to a regression which appeared in kernel 2.6.39.3 and later. Kernel bugzilla is down right now but the bug is referenced here : https://bugzilla.kernel.org/show_bug.cgi?id=42012 From the netdev archive, a patch has been proposed to fix the regression : http://www.spinics.net/lists/netdev/msg173766.html -- Cyril Bonté
