[Lxc-users] kernel.shmmax in LXC

[Jan Den Ouden]

Hi,

About a week ago I posted exactly the same question on this list, but I
didn't get any responses. I have googled high and low for the answer to
this, but no result. It's not related to capabilities, because you can only
drop capabilities, not add them. It's not related to the cgroup memory
controller, because that seems to deal with total memory, not shared
memory. Therefore, I think it's a bug.
