    As I've been pointed our cgroups could play some role -


mhh I don't think I'm using Control Groups at all....
[root@orapr2 ~]# rpm -qa |grep group
[root@orapr2 ~]#

[root@orapr2 ~]# ll /etc/cgconfig.conf
ls: cannot access /etc/cgconfig.conf: No such file or directory


    so lets repeat with  /proc/*/mountinfo


[root@orapr2 ~]# cat /proc/*/mountinfo > /tmp/proc.log
cat: /proc/33700/mountinfo: Invalid argument
cat: /proc/33735/mountinfo: No such file or directory

[root@orapr2 ~]# wc -l /tmp/proc.log
55050 /tmp/proc.log

  [root@orapr2 ~]# grep 253:49 /tmp/proc.log
[root@orapr2 ~]#


    Also check  /proc/swaps ?


  [root@orapr2 ~]# cat /proc/swaps
FilenameTypeSizeUsedPriority
/dev/sda2                               partition167772120-1


So I'm afraid you will need to open a RHEL support ticket to get all the diagnostic (sosreport) - since if this is production system,
all further advices may lead to some problems.
