hi!
I have a container, which init process uses 100% CPU.
If I create a strace dump from it:
open("/dev/ptmx", O_RDWR|O_NOCTTY) = -1 EMFILE (Too many open files)
close(1022) = 0
close(1023) = 0
pipe([1022, 1023]) = 0
I saw it before. However other container works fine beside it.
Is this a bug, or I did something wrong?
I created the container with the command 'lxc-create -n log0 -t ubuntu
-- -r precise' .
fs.file-nr = 3328 0 805183
In the container there is a realy minimalized installation, with a mysql
instance, apache etc, nothing in production and not in use.
