Hi Guys,

Be warned of SL6.8 fastbugs if you're using cgroups...

Cheers

Same here.
Hey ! This seems SL specific... !?

I installed this one manually : CentOS/6.8/updates/x86_64/Packages/libcgroup-0.40.rc1-18.el6_8.x86_64.rpm

[root@dev7247 ~]# cat /etc/redhat-release
Scientific Linux release 6.8 (Carbon)

[root@dev7247 ~]# rpm -qi libcgroup
Name        : libcgroup                    Relocations: (not relocatable)
Version     : 0.40.rc1                          Vendor: CentOS
Release     : 18.el6_8                      Build Date: Tue 12 Jul 2016 06:27:20 PM CEST
Install Date: Wed 27 Jul 2016 05:15:28 PM CEST      Build Host: worker1.bsys.centos.org
(...)

And cgroups seem to still work whereas they failed with the SL RPM :
[root@dev7247 ~]# service cgconfig restart
Stopping cgconfig service:                                 [  OK  ]
Starting cgconfig service:                                 [  OK  ]

?

Regards

Greetings,

I discovered the exact same thing. I fully updated to 6.8 and rebooted
into the new kernel. I haven't filed a bug report against it yet as I
didn't have time yesterday to really dig into it. My "workaround" was to
"yum downgrade libcgroup" on all my hosts until I could figure it out.
