      2.2-BETA (amd64)
      built on Fri Oct 10

      Uptime was around 4 days, 8 hours.

      For no apparent reason radvd terminated and IPv6 DHCP-PD addressing was lost.

      There was no interface reset or Cable Modem reset or loss of signal on DOCSIS side.

      I have Gateway Monitoring (apinger) disabled for IPv4 and IPv6.  I have run that way on 2.1.x for several months, due to the loss of IPv6 addressing if there is even a short gateway event.

      I assume radvd restarted because it is a service monitored by Service Watchdog.  But that seems kind of pointless since restarting it does not bring back the lost IPv6 addressing.  A WAN interface release/renew did not help, ended up rebooting.

      The logs are below.  No other system or external event at the time radvd exited.
