      Description

      A couple times recently the Evergreen database has held an election. This is unusual, and in the second case caused a brief outage. This might either indicate some bug in our code, or potentially some task is putting unusually high load on the database.

       

      The first was 4/26 around 3pm ET. The second was 4/27 at 9:42pm ET.

       

      The questions we should investigate include:

      1. Is there some task that was running during both times?
      2. Is there some increase in access to some API endpoint?
      3. Is there anything useful on the APM dashboard that might be a clue?
      4. Do the logs indicate some kind of error with the database itself?
