Dear list member.

I have tried to setup the machine for this traffic but it looks to me
that was not successfully.

Conf:

When I activate the aio, nginx and xfs crashes, that's why aio is not
active.
In one include file we have the following.
####
location ~ recent {
add_header Cache-Control "no-cache";
}
####
sysctl -a
http://download.none.at/sysctl.txt
lsmod:
http://download.none.at/lsmod.txt
dmesg:
http://download.none.at/dmesg.txt
On this machine also runs a postgresql and php-fpm but the current
traffic is from delivering of pictures from the file system.
/dev/mapper/pada2_vg-pada2_lv on /home/<datadir> type xfs
(rw,noatime,nodiratime,attr2,inode64,noquota)
Thanks for help.
Best regards
Aleks
