    Description

      Dear Mongo,

      I'm writing regarding mongo WriteConflictException. We're using this server in production and problem happens to often.

      Here is what we got:

      • OS --> Debian Stretch 9.4
      • RAM --> 125 GB
      • CPU --> Intel Xeon CPU E5-2620 v4 2.10GHz (32 cores)
      • HDD --> 916 GB (we're not using XFS, instead we're using EXT4)
      • MongoDB --> Version 3.6.3
      • Installation is done following this manual (https://docs.mongodb.com/manual/tutorial/install-mongodb-on-debian), package libssl1.0.0:amd64 (1.0.1t-1+deb8u7) is also installed.
      • Mongo service is started using systemd service with numactl

      In attachment I'm providing you a part of log that looks suspicious to me.

      If you need any additional information, please let me know.

      Thank you very much
