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?
