Hi,
Run sysctl -w kern.maxfiles= to what ever value is needed. To get it
updated at startup you can put a line like kern.maxfiles= in
/etc/sysctl.conf to have the change on every reboot. You may also have to
edit /etc/login.conf and adjust any openfiles= lines that might be
lowering the per-process limit.
By default the openfiles value is unlimited OR infinite.

Subject: kernel option to increase max open files
Date: Thu, 16 Oct 2003 10:09:14 -0700
Hi, folks.
I've got a 2.2.2 machine which I can't currently upgrade, due to funding
issues. This machine handles a lot of mail, and I am lately finding
dmesg output to be full of file: table is full messages, and entries
like these in the sendmail log:
SYSERR(UID0): readqf: cannot open dfAAA29006: Too many open files in \
system
SYSERR(UID0): Cannot open hash database /etc/aliases: Too many open \
files in system
So I figure I need to increase the max number of open files available.
I've looked around, and it appears I have two different options:
1) Kernel option options OPEN_MAX=### which sets the max number
of open files per user (which would be 'root' in this case, as that's who
sendmail runs as).
2) a login.conf class setting assigned to root. The 'openfiles' setting
seems
somewhat equivalent to the OPEN_MAX option. However, I am not certain
that limits set in login.conf apply to a process being run by a user that
didn't log in (sendmail being started by init at boot, rather than from
root's login session).
I welcome any thoughts/advice on this matter, as I don't want to try either
of these changes without having done due diligence.
Thank you,
-John
