Re: OpenBSD and Apache
This is due to the way OpenBSD allocates vnodes. There is a number in the
kernel called desiredvnodes, which is the number of vnodes that you can
have open simultaneously.
For the default configuration, desiredvnodes = 1000. The quantity is determined
in /usr/src/sys/arch/<arch>/compile/<build>/param.c.
OpenBSD will allocate up to 2*desiredvnodes (or 2000) before it signals that
it's vnode table is full.
Recompile the kernel, raising desiredvnodes or figure out why you have
1000 files open simultaneously and try to reduce that.
