      A MongoDB workload that inserts one document in a database and then repeatedly updates the document causes the collection file in WiredTiger to grow in proportion to the number of updates.

      I can only reproduce this in replica sets.  When running against a single mongod, the collection file doesn't grow past a few dozen KB.

      I am attaching simple.sh and simple.js which reproduce the problem.

        1. simple.js
          0.3 kB
        2. simple.sh
          0.8 kB
