Permissions on /dev/null change randomly
Issue
The permissions of /dev/null are usually 660, but we're occasionally getting errors accessing it:
-bash: /dev/null: Permission denied
Oracle database instances might become inaccessible when we run into this error. When we force the permissions to 666, the database becomes accessible again.
