this file only takes action when pam_limits is used.
can you grep your /etc/pam.d for limits?

PS: I hate to say it, but it seems the neat architecture of the heartbeat-VM is not appreciated by
    current linux distros. There is just too much to do for the average user to make use of it.
    Also, users need some kind of Root to be able to enable the rtprio, which is not a good idea.
    Is there any way to get away without changing rtprio?
