      I am running YCSB on a 3 node setup.
      Node 1) Runs 3 config servers
      Node 2) Runs mongod and mongos
      Node 3) Runs YCSB clients.

      I insert 30 million rows as mentioned in the blog post https://www.mongodb.com/blog/post/performance-testing-mongodb-30-part-1-throughput-improvements-measured-ycsb here. The row has 1 field of 100 bytes of data. After inserting the data, I run YCSB short range scan with scan length of 50. During the scan my mongod process went down and in the mongod log, I saw:
