Re: 3.2.5 comm_open: socket failure: (24) Too many open files

I made sure and squid logs the current available FD from the OS and not just using compiled options.

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?

Hey,

It's probably the linux ulimit settings.
run:
ulimit -Sn
ulimit -Hn

If there is a limit of 1k in the list you will need to change it since squid
bound to the OS limits.

Squid is configured with 16384 FD and it is only using 1k, it seems it
is still complains about running out of FD. Is there a regression from
3.2.5 -》 3.2.2 ?
