    Description

      Hi,

      since a few weeks now, one of my mongodb server randomly crashes. Sometimes, it occurs after a week days without issues, sometimes after a few seconds only.
      The stacktrace is always quite the same (see attachment).
      My configuration is :

      systemLog:
          verbosity: 0
          quiet: false
          path: /var/log/mongodb/mongodb.log
          logAppend: false
          logRotate: rename
          destination: file
          timeStampFormat: iso8601-local
      processManagement:
          fork: false
      net:
          port: 27017
          bindIp: 127.0.0.1,10.0.1.98
          ipv6: false
          http:
              enabled: true
              JSONPEnabled: false
              RESTInterfaceEnabled: false
      storage:
          dbPath: /var/lib/mongodb
          indexBuildRetry: true
          journal:
              enabled: true
          directoryPerDB: false
          engine: wiredTiger
          wiredTiger:
              engineConfig:
                  cacheSizeGB: 8
                  statisticsLogDelaySecs: 10
                  journalCompressor: snappy
                  directoryForIndexes: false
      operationProfiling:
          slowOpThresholdMs: 100
          mode: slowOp
      replication:
          replSetName: cluster1
      

      It's always the same node that is failing. I haven't trashed the container yet to test if it can be caused by a corrupt file somewhere. This is my next step but I prefer to wait if you need some details about this issue.
      Thanks.
