 Description   

The Linux OOM killer can kill mongod/mongos in certain circumstances such as:

  • when having no (or too little) swap
  • having overcommit memory to 2 and a non optimal overcommit ratio.

The production notes currently only have a small mention of this under "swap" which doesn't provide any guidance on appropriate swap or sysctl settings to play well with the OOM Killer:

Assign swap space for your systems. Allocating swap space can avoid issues with memory contention and can prevent the OOM Killer on Linux systems from killing mongod.
