      This case is being raised from WT-3207 - in the latest 3.4.6 release, the bottleneck appears to have moved from CPU to disk.

      Image 1 - the database is dropped (09:02:47) and the queries, updates have dropped off.

      Image 2 - Recovery - at 09:04:45 the primary recovers and starts processing requests. Note the list Databases that returned after a long period of time.

      A new run with diagnostics.data to follow - Can I have a secure link to submit it to?
