Sorry for the delay in responding, I was doing a bit of traveling.

I would suggest trying a newer kernel if possible.  Starting with
v4.10 and continuing up through v4.13 there was substantial work done
that would affect the audit backlog and kernel/auditd connection; if
you can try a v4.13 Linux kernel I would highly recommend it.
