Question SELinux preventing php/7.1/bin/php-cgi

[wwwAndries]

Hello,

I'am seeing a lot of these messages in audit.log of a CentOS 6.8 with Plesk Onyx 17.0.17 Update #15:

1. SELinux is preventing /opt/plesk/php/7.1/bin/php-cgi from search access on the directory /sys
2. SELinux is preventing /opt/plesk/php/7.1/bin/php-cgi from name_connect access on the tcp_socket

Where is causing these messages and should I allow search acces for the directory /sys?
To prevent message 2, I've to set setsebool -P allow_ypbind 1.

Are there security risk involved?

Thanks.
