Can you please try to upload the contents of that folder again using our Secure Uploader? Thank you, Danny daniel.hatcher commented on Mon, 3 Dec 2018 22:25:10 +0000: Hello Mamta, I have created a Secure Uploader for any files that need to be uploaded as a result of this investigation. Please rest assured that these files can only be accessed by MongoDB engineers and will be deleted after some time. I have uploaded what you sent me via email and will look through them to continue my analysis. Thank you, Danny mamta.kumari commented on Mon, 3 Dec 2018 20:27:46 +0000: Hi Denny both files sent you over mail Thanks Mamta daniel.hatcher commented on Mon, 3 Dec 2018 16:36:34 +0000: Hello Mamta, However, if you would like us to look into it further, please provide the mongod log files covering the incident and the "diagnostic.data" folder located under the $dbpath. Thank you, Danny daniel.hatcher commented on Mon, 3 Dec 2018 15:09:48 +0000: Hello Mamta, Unfortunately, I do not see any problems with MongoDB itself from what you've posted. If there was a problem, MongoDB would have printed an error message or at least indicated it was shutting down. When those messages do not exist it means that the process was hard-killed by something else on the server. I'd recommend checking your system logs to see if the Operating System decided to kill the process for some reason. Thus, I do not see anything to indicate a bug in the MongoDB server. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-user group. See also our Technical Support page for additional support resources. Thank you, Danny mamta.kumari commented on Sun, 2 Dec 2018 05:51:08 +0000: hello Denny, At first, when mongo db gets shut down I guess it shuts down hard, it is not printing anything. when I restart... it is printing this ommand config.$cmd command: update \{ update: "system.sessions", ordered: false, allowImplicitCollectionCreation: false, $db: "config" } numYields:0 reslen:97949 locks:{

The way MongoDB was stopped should help determine why it stopped in the first place. Please provide a snippet containing the last operation you provided up through the server restart. This snippet should include any shutdown-related messages.
