#oo-accept-node


Actual results:
The similar errors are given out at random

Output:
FAIL: 525ce8455f101a5da90002f4 has a process missing from cgroups: 9385 cgroups controller: freezer
FAIL: 525ce8455f101a5da90002f4 has a process missing from cgroups: 9393 cgroups controller: freezer
FAIL: 525ce84c5f101a395f0019a1 has a process missing from cgroups: 10102 cgroups controller: net_cls
FAIL: 525ce84c5f101a395f0019a1 has a process missing from cgroups: 10106 cgroups controller: net_cls
FAIL: 525ce84c5f101a395f0019a1 has a process missing from cgroups: 10102 cgroups controller: freezer
FAIL: 525ce84c5f101a395f0019a1 has a process missing from cgroups: 10106 cgroups controller: freezer

That means some processes are not limited by cgroup.

Expected results:
Should show no error!! 

Additional info:
If the above error message is shown, restart cgred service, re-run oo-accept-node, it works fine.

I check this problem on devenv__4247 and puddle [2.0.2/2014-01-16.1], Now the problem can not be reproduced.

The cgred service has been started after the cgconfig service. So the problem can not be reproduced.
