    • Type: Bug
    • Status: Closed
    • Priority: Major - P3
    • Resolution: Fixed
    • Affects Version/s: 3.6.0
    • Fix Version/s: 3.6.1, 3.7.1
    • Component/s: Sharding
    • Labels:
    • Backwards Compatibility:
      Fully Compatible
    • Operating System:
      ALL
    • Backport Requested:
      v3.6
    • Steps To Reproduce:
      Hide

      1. Mongo sharded cluster 3.6.0 with 2 replicas.
      2. Launch mongos.crash.snippet.java against mongos.
      In snippet you can check number of inserts (NUMBER_OF_INSERTS), if it equals 87522 or higher mongos crashes each time you try to insertMany.
      You get different stacktraces depends on number of inserts.

      Description

      We upgraded mongo sharded cluster from 3.4.10 to 3.6.0 version and mongoses started to crash from insertMany operation, if its size is bigger than maxBsonObjectSize.
      It seems that it begins because of upping maxWriteBatchSize in 3.6.0 to 100000.
      Got two different stacktraces:
