    Description

      Symptoms: mongos listen port, but don't serve client requests for few hours (until restart). Nothing suspicious in the logs found.

      I was make core dump and backtrace for all threads (backtrace file is attached to this issue).

      How often: around twice a month per production environment.

      Version:

      mongos version v4.0.4
      {{ git version: f288a3bdf201007f3693c58e140056adf8b04839}}
      {{ OpenSSL version: OpenSSL 1.0.2g 1 Mar 2016}}
      {{ allocator: tcmalloc}}
      {{ modules: none}}
      {{ build environment:}}
      {{ distmod: ubuntu1604}}
      {{ distarch: x86_64}}
      {{ target_arch: x86_64}}

      Topology:

      • single shard cluster
      • 3-nodes configuration replicaset;
      • 4-nodes shard replicaset;
      • mongos instance on each client host.
