For continuous insertion of data in mongo using Java API (MongoClientOptions.Builder) create multiple connections. These connections don't even kill and after reaching to a certain limit you mongodb get crashed. I am linking http://stackoverflow.com/questions/29469317/checking-mongodb-created-connection. I hope it to be resolved as soon as possible. |

sanjeev_yadav248, the SERVER project is for reporting bugs on the MongoDB server, and without logs that can help us determine if there's a bug there's not much we can do. I'm going to close this ticket for now, but if you can produce evidence of a sever bug please follow up on this ticket and we'll reopen it for investigation. Note that 1000 connections is a small number, so if a machine is having issues with it I'd recommend looking at OS resources (does the machine have enough RAM) and limits (e.g.: is mongod allowed to open more than 1024 files) to track down the source of the problem. Regards, |

Since it was production machine, we have given it to particular vendor for data recovery. So I don't have logs right now. But the same issue I am still facing on amazon AWS server. Every day my connection in mongo increases. Once it reached around 1000 connections, I am afraid it will crash. I have attach my db.serverstatus() in text file. You can see around 105 connections are already created. I have already mentioned since static behavior only one instance should be created. On java side its loaded only once but on mongodb side connections are increasing continuously. |

sanjeev_yadav248, as William and Ross mentioned in stack overflow the number of connections are expected, but they should not crash mongod – can you please upload logs for the server from startup until the crash you mention? Thanks, |
