No, and no errors are shown for it either:

# ifconfig lo
lo Link encap:Local Loopback
          inet addr:127.0.0.1 Mask:255.0.0.0
          UP LOOPBACK RUNNING MTU:16436 Metric:1
          RX packets:196907 errors:0 dropped:0 overruns:0 frame:0
          TX packets:196907 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0

All *seems* well. Just that 30-second period of messages and then silence.

Thanks for the response.
