 I've got Tor installed on a modern Gentoo linux virtual machine, with the
 nat-pmp and upnp USE flags enabled in Portage. I've enabled port
 forwarding in my torrc with: "PortForwarding 1." Port forwarding appears
 to work as expected, as I can see that the DIRPORT 9030 and the ORPORT
 9001 are forwarding via miniupnpd running on my OpenWRT router to the tor
 relay host. The logs on the router show the port forwarding succeeding via
 nat-pmp.
 However, I am getting log statements every 5 minutes form tor which look
 like this when seen in ARM: "[NOTICE] Failed to terminate process with PID
 '9053'".
 When I see these statements, I check for the PID in question and don't
 find it running. I don't have a "PortForwardingHelper" option set in the
 torrc at all, but I suspect that these PID logging statements are coming
 from something port-forwarding related. Maybe the helper is quitting
 unexpectedly?
 I can recompile without port forwarding and do it manually, but before I
 did that I figured I would write up this issue and see if I can help in
 testing and debugging.
