      The primary's log file is attached in: mongod.log
      Search for "c999d161-5c6a-4c91-b721-e2a6d9a6c3af" to find the session operations for the failed test.

      If I understand the server logs correctly it looks a document is returned for the primary_coll.find() so PyMongo's cursor should not be empty:

      Marking as low priority until I see this failure again or find more information.
