Hi,
I have a Replica Set with 3 members (1 primary and 2 secondaries), and one of the secondaries was working just fine and thrown the following error
2018-03-12T11:03:54.868-0400 E REPL [repl writer worker 13] writer worker caught exception: :: caused by :: 84 key/value already in index on: { ts: Timestamp 1520867034000|8, h: 287037468373256260, v: 2, op: "u", ns: "Sitecore_analytics_PROD.Interactions", o2: { _id: BinData(3, EFC3DD1A15B75442986344FDE9CC71EB) }, o: { $set: { ContactVisitIndex: 2 } } }

***aborting after fassert() failure
After that the MongoDB cannot start anymore, and keep throwing the same error!
How can I determine the root cause of it? Is there a way to prevent? How to solve it?
