| Description |
|
zbigMapReduce.js can roll over its oplog if the inserts go fast enough and the fetching is a bit slow, leading to unrecoverable rollbacks. Reducing the data size to 50MB total or increasing the oplog size to 250 MB (or something in the middle) would be good. |

Given the current issues with this test getting OOM killed, reducing the number of inserted documents may be the better solution. |
