>Description:

It seems to me that varnish drops root priviledges before attempting an mlock(2), thus failing it.

>How-To-Repeat:

# cd /usr/ports/www/varnish
# make install clean
# echo 'varnishd_storage="file,data,100M"' >>/etc/rc.conf
# /usr/local/etc/rc.d/varnishd forcestart
Starting varnishd.
storage_file: filename: /usr/local/varnish/$HOST/data size 100 MB.
Using old SHMFILE
Notice: locking SHMFILE in core failed: Operation not permitted

>Fix:

Work-around is:
# echo 'varnishd_user="root"' >>/etc/rc.conf

Host with the problem is a:
FreeBSD $HOST 7.0-STABLE FreeBSD 7.0-STABLE #2: Sat May 31 09:57:05 CEST 2008     root@$HOST:/usr/obj/usr/src/sys/GENERIC  amd64
