[lxc-users] Bug bug bug

[CDR]

There is something very wrong with LXC in general, it does not matter the
OS or even the kernel version. My OS is Ubuntu 14.04.
I have a Centos 6.6 container with mysql and 50 instances of Asterisk 12.0,
plus opensips.
The memory is limited to 100G, but it does not matter if I limit it or not.
It crashes when I start the 50 Asterisk processes.
​ The err​or message is below.

MySql starts fine and uses large-pages, memlocked. It uses 60G, so there is
plenty of available memory left.

 free -g
             total       used       free     shared    buffers     cached
Mem:           177        163         13          0          0         97

​I tried the same ​container in Fedora 21 and the outcome is identical, and
it matters not if the technology is plain lxc or libvirt-lxc.

This is my containers config:
 lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0
lxc.mount.entry = sysfs sys sysfs defaults  0 0


lxc.tty = 4
lxc.pts = 1024
lxc.cgroup.devices.deny = a
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
lxc.cgroup.devices.allow = c 4:0 rwm
lxc.cgroup.devices.allow = c 4:1 rwm
lxc.cgroup.devices.allow = c 1:9 rwm
lxc.cgroup.devices.allow = c 1:8 rwm
lxc.cgroup.devices.allow = c 136:* rwm
lxc.cgroup.devices.allow = c 5:2 rwm
lxc.cgroup.devices.allow = c 254:0 rwm
lxc.cgroup.devices.allow = c 10:137 rwm # loop-control
lxc.cgroup.devices.allow = b 7:* rwm    # loop*
lxc.cgroup.memory.limit_in_bytes =  107374182400
lxc.mount.auto = cgroup

lxc.utsname = parallelu
lxc.autodev = 1
lxc.aa_profile = unconfined

lxc.network.type=macvlan
lxc.network.macvlan.mode=bridge
lxc.network.link=eth1
lxc.network.name = eth0
lxc.network.flags = up
lxc.network.hwaddr = 00:c8:a0:7d:84:cf
lxc.network.ipv4 = 0.0.0.0/25
