RE: https://github.com/mongodb/mongo/blob/r3.0.0/src/mongo/db/repl/rs_rollback.cpp#L587
During the rollback process we print an error if a document that is eligible for deletion / addition to rollback file does not exist in the given collection. At present there is no indication as to which document encountered this scenario. Please print the _id value and namespace in question with this error, to allow for traceability when issues are encountered.
// Add the doc to our rollback file BSONObj obj; bool found = Helpers::findOne(txn, ctx.db()->getCollection(doc.ns), pattern, obj, false); if (found) { removeSaver->goingToDelete(obj); } else { error() << "rollback cannot find object by id"; }
