Thanks.  I am already running (half of) that patch that fixes
security_context_to_sid_core(), and it indeed seems to fix the random
oom's.

However, I was asking about the (corner?) case where the system
legitimately needed to call the oom-killer.  Do the above AVCs
('sys_rawio', 'sys_admin', and 'sys_resource') indicate an issue?
They did not appear to interfere with the killing of the
processes......
