Archiving was last executed without error X days

I have a multi server multi instance footprint of Piwik. I have an issue where my archive process is completing but it still shows that it was last archived without error many days ago. As far as I can tell there are no errors occurring (as indicated in the log summary at the end), and yet it seems there errors somewhere. My question is how to I fix this issue so the log resets itself back to zero days without error?
INFO [2017-04-04 21:49:38] - Archiving was last executed without error 57 days 13 hours ago

My Piwik system overview:

  • 4 x Piwik web servers, each with 10 separate named instances of Piwik (/p01, /p02, /p03 etc…)
  • Each Piwik instances hosts analytics for about 500 to 2000 separate websites
  • Each web server has a dedicated MySQL server.
  • Each web server has a dedicated “archives” server for managing archives via CRON every 12 hours.
