MongoDB version 3.6.
When auditing is enabled, aggregation query with $out, fails with the error "Size must be between 0 and 16793600(16MB) error" even though there is no document in the collection that is greater than 16MB.
For example, with auditing enabled on mongod, when the following query is executed:
| db.collection.aggregate([ {$match:{}}, {$out:"collection2"} ],{allowDiskUse:true}) |
it throws this error:
assert: command failed: { "operationTime" : Timestamp(1529677911, 2), "ok" : 0, "errmsg" : "insert for $out failed: { lastOp: { ts: Timestamp(1529677911, 1), t: 4 } , connectionId: 202, err: \"BSONObj size: 16793954 (0x1004162) is invalid.

When auditing is not enabled, the aggregation query succeeds.
