    Description

      A DB-specific write lock saw a one-time ~213 day spike in micros between a 1 minute span. (37008987922471 -> 55455750947083)

      First observed in MMS as a 34m spike in lock %, but ultimately traced back to serverStatus changes between consecutive MMS agent pings.

      Believe this has been reported by other clients on MMS side; will update ticket if I find more instances of lock % spikes.
