Soft lockup occurs where setsebool is trying to take the selinux policy rwlock that has been taken by the task itself in the same context (DEADLOCK)

Issue

• When I run setsebool -P httpd_can_network_connect 1, soft lockups occur where setsebool is trying to take the selinux policy rwlock that has been taken by the task itself in the same context.
