[gentoo-hardened] denied resource overstep... for RLIMIT_MEMLOCK

[Grant <emailgrant@gmail.com>]

One of my Blu-Ray rips won't play and there is a steady stream of
"Error while decoding frame!" messages in mplayer's output when I try.
 I just noticed that each time I try to play the movie, I get another
one of these in dmesg:

grsec: denied resource overstep by requesting 135168 for
RLIMIT_MEMLOCK against limit 32768 for /usr/bin/mplayer[mplayer:22122]
uid/euid:1000/1000 gid/egid:100/100, parent /bin/bash[bash:22095]
uid/euid:1000/1000 gid/egid:100/100

I tried:

paxctl -m /usr/bin/mplayer

but it doesn't seem to make any difference.  Does anyone know how to
fix this?  How can I undo what I did with the above paxctl command
since it doesn't seem to be helping?
