Re: [squid-users] 3.2.5 comm_open: socket failure: (24) Too many open files

So you are saying even squid is configured to use 16384 fd, it
couldn't because limit is 1024?

That's kind of confusing, I tried to use ulimit -n 16384 as root to
raise FD limit now, will report back.

Maybe squid can probe at start and warn about mis-matching fd limits?
