Let me first explain the scenario first!
I've installed mongo 3.6 and it was running fine but then I decided to upgrade, so I just took the backup using mongo tools. I removed and purged all the mongo packages and reinstalled the latest version. Restored the backup edited few changes in unit file and conf file.
[Unit] Description=MongoDB Database Server Documentation=https://docs.mongodb.org/manual After=network.target [Service] User=mongodb Group=mongodb EnvironmentFile=-/etc/default/mongod ExecStart=/usr/bin/mongod --config /etc/mongod.conf PIDFile=/run/mongodb/mongod.pid Restart=always RestartSec=1 # file size LimitFSIZE=infinity # cpu time LimitCPU=infinity # virtual memory size LimitAS=infinity # open files LimitNOFILE=64000 # processes/threads LimitNPROC=64000 # locked memory LimitMEMLOCK=65536 # total threads (user+kernel) TasksMax=infinity TasksAccounting=false # Recommended limits for mongod as specified in # https://docs.mongodb.com/manual/reference/ulimit/#recommended-ulimit-settings [Install] WantedBy=multi-user.target
I was running two mongo instances, copied everything separately (I'm sure, I did this perfectly) as it was the same when mongo 3.6 was running.
Now, sometimes my mongod instance is killed:
Sep 11 09:28:05 mlnode systemd[1]: mongod.service: Main process exited, code=killed, status=6/ABRT Sep 11 09:28:05 mlnode systemd[1]: mongod.service: Failed with result 'signal'.
I've looked into the mongo logs as well but I was unable to understand what is the exact reason also I've looked at other Jira threads which says maybe this is an issue of MEMLOCK limits, I've corrected that still, the problem persists.

I want urgent help please! If anyone wants additional information then I'm ready to provide ASAP.
Thanks
