Hi,
Some question about openfiles limit...
I can't understand how openbsd counts open files.
Ex.
# sysctl kern.nfiles ; fstat | wc -l
kern.nfiles=2470
3594
What's the difference between kern.nfiles and fstat?
Secondly, I set class limits for mysql for testing:
# rcctl get mysqld
mysqld_class=mysqld
mysqld_flags=
mysqld_timeout=30
mysqld_user=root
# userinfo _mysql
login _mysql
passwd *************
uid 502
groups _mysql
change NEVER
class mysqld
gecos MySQL Account
dir /nonexistent
shell /sbin/nologin
expire NEVER
# getcap -f /etc/login.conf mysqld
mysqld: :openfiles-cur=128: :openfiles-max=256:
# su _mysql
# ulimit -a
time(cpu-seconds) unlimited
file(blocks) unlimited
coredump(blocks) unlimited
data(kbytes) 33554432
stack(kbytes) 8192
lockedmem(kbytes) 10825182
memory(kbytes) 32472388
nofiles(descriptors) 128
processes 1310
So why mysql is allowed to open more than 256 files:
# fstat -u _mysql | wc -l
998
Can anyone help with that?
# uname -a
OpenBSD zeus.apisoft.pl 5.9 GENERIC.MP#1888 amd64
