Re: epoll on squid

I suspect what is hapenning is that you do not have '--disable-select
--disable-poll' in your configure line. Unfortunately with the way
configure in squid is setup right now, if you enable kqueue or epoll it
will still try to enable select or poll. I will try to fix this, but
for now I think specifically disabling select and poll should do it.
