CentOS - May 2014 - Centos 6.5

Hi,

I am using centos 6.4. i am trying to update
/proc/sys/fs/epoll/max_user_instances but it seems like it is not supported
anymore in /etc/sysctl.conf.

How do we update max_user_instances on centos 6.4?

Thanks & Regards

[user at server ~]# find /proc -name max_user_instances
