Thanks for your report liar666. Depending on the size of your dataset MongoDB may require significant amounts of memory, and if the OS detects too much memory usage by any process the OOM killer may step in and kill that process.

If the OOM killer is not working as expected this is not a bug in MongoDB itself. You may also want to add more swap to your system and/or follow up with your OS vendor.

Since this is not a bug in MongoDB I'm resolving this ticket, as the SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag, where your question will reach a larger audience. A question like this involving more discussion would be best posted on the mongodb-user group.

Regards,
Ramón.
