Falha ao ajustar a pontuação de renderizador do OOM com o pid X: Permissão negada

Question

Não sei exatamente o que está causando, mas estou recebendo o seguinte erro:

Apr 11 12:30:00 X alacarte-made-2.desktop: [1712:1735:0411/123000:ERROR:zygote_host_impl_linux.cc(162)] Failed to adjust OOM score of renderer with pid 2897: Permission denied

depois de atualizar para a versão beta mais recente (51), agora recebo isso:

Meu sistema:

$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 
$ uname -a
Linux X 3.10.0-327.13.1.el7.x86_64 #1 SMP Thu Mar 31 16:04:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
$ rpm -q google-chrome-beta
google-chrome-beta-51.0.2704.22-1.x86_64
$ 

Como alguém resolve esse problema?
