After upgrading from 2.2 to 2.4.1 i am seeing a very usage of the memory. The memory (8GB) usage stays at 40-50% most of the time and gradually goes upto 98% !! Please help urgently as it is impacting my production |

The release candidate version 2.4.2-rc0 includes fixes for some memory leaks in JavaScript, which are particularly evident when running MapReduce but also affect other JavaScript usage. Can you try version 2.4.2-rc0 and see if the memory usage is better? |

I just reverted back to 2.2.* and its working fine to start with. I will wait for a full day and let you guys know. But as of now it looks like a problem with the 2.4.1 version. Someone kindly help us resolve this. Ronak |

Hi, I am running a mongod server and am experiencing the same problem running on Ubuntu 12.04. I have a replica set with two nodes and an arbiter. This issue has occurred at least three times since upgrading from 2.2.3 to 2.4.1. Currently when the primary node gets to high memory usage I step down the primary and restart the mongod process. Any idea what the problem might be? |

I do have Map-Reduce functions, but its only used very few times. The primary queries are Read and Geo spatial queries. |
