Hello, the error is still bugging me, very regularly every two weeks the 
log is full and the proxy doesn't respond. Extremely annoying.
Right now, after a apachectl restart, it's logging one per second but 
net.inet.ip.intr_queue_drops is 0. After I killed apache and restarted it 
no errors occur, but I'm sure it'll start again in two weeks and fills the 
errorlog until it doesn't work anymore.

I'll recompile apache with WITH_KQUEUE_SUPPORT and give some feedback. Has 
anyone else had luck to observe this problem in the meantime?

Thanks,

-Harry
