--- Begin Message ---Hi! I had look at it this together with Dhaval Giani at Linux Kongress in Nuremberg. Dhaval asked me for shambhala:~> cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled ns 0 1 1 cpuacct 1 2 1 devices 2 2 1 freezer 0 1 1 blkio 0 1 1 which pointed out that my kernel had no group scheduling support. That can't work with: 45 mount { 46 cpu = /mnt/cgroups/cpu; 47 cpuacct = /mnt/cgroups/cpuacct; 48 devices = /mnt/cgroups/devices; 49 } Thus I changed this too: 45 mount { 46 # cpu = /mnt/cgroups/cpu; 47 cpuacct = /mnt/cgroups/cpuacct; 48 devices = /mnt/cgroups/devices; 49 } Which unlike commenting out the whole block works fine. The error message of the config parser could be more helpful in that case, cause the problem is the not a parsing issue, but a lack of kernel support, and as such not a real syntax error in the configuration file, but that is an upstream issue. Thus closing. Thanks, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
