[Lxc-users] init keep files opened

[Papp Tamas]

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.
