I'd patch it to syslog errno and other information to locate the syscall
that's failing. Did socket fail? Did the send fail? Does it work in permissive

I would also verify that your loaded SELinux policy is not blocking
the CAP_AUDIT_WRITE capability or the netlink_audit_socket:nlmsg_relay
permission.
