Thanks for the suggestion. I'm getting other audit events from sshd without restarting ssh. It's just the accept syscalls that do not show up until after I restart ssh:
type=SYSCALL msg=audit(1480714641.465:54): arch=c000003e syscall=43 success=yes exit=5 a0=3 a1=7ffce3b031b0 a2=7ffce3b0319c a3=0 items=0 ppid=1 pid=2602 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="sshd" exe="/usr/sbin/sshd" key=(null)
I think that indicates the kernel is sending up audit messages. My question is why the above message fails to come up until after I've restarted ssh.
