Running FreeBSD 4.3 (I know - upgrade on the way, but would like to know
what's going on here for future ref), on AMD Athlon MP 1600 (1393.79-MHz
686-class CPU) with 1.5 Gb RAM. Ran up against 'too many files' problem,
dropped packets, maxing out mbuf's, proc files, etc.
Attempted to compile custom kernel based on GENERIC only by changing
maxusers from 32 to (first) 512, then 256, then 128. No matter what,
system rebooted with 32 maxusers, 4096 mbugs, 1024 max mbuf clusters,
1024 maxfiles. Can reset maxfiles via sysctl, but why won't maxusers stick?
Have tried building both with:
# /usr/sbin/config MYKERNEL
# cd ../../comple/MYKERNEL
# make depend
# make
# make install
# reboot
and with
# cd /usr/src
# make buildkernel KERNCONF=MYKERNEL
# make installkernel KERNCONF=MYKERNEL
# reboot
No discernable error messages.
What am I missing?
First, I guess, be sure that it's using the file
you're specifying.
Next, hmm, per the Handbook, have you tried "0" (to let
the system "auto-tune" itself?)
That said, after 4.5*, you can set this variable in
/boot/loader.conf ... I've no idea ATM whether or not
this behavior was "MFC'ed" back into your code stream
or not ... (surely you're not running 4.3 UNPATCHED<?!!>)
you may wish to check /boot/defaults/loader.conf for
evidence of this theory, and, if you find it, give that
a try as well.
HTH,

*This information isn't in the handbook (I don't think ...
I sent a doc PR a day or two ago on it due to a post
here by someone who was having troubles in the same
area, I guess...).
