      Description

      We are running a test server using v3.0.6 with WiredTiger in standalone mode, the docs are like:

      {"_id":"Article Title", "status":0}

      There are about 5 million docs in the collection, and we call findAndModify to get the doc and set the "status" field to 1 every second, from two other test servers.

      After running for about 2 hours, the mongod crashed and we got these errors:
