| Description |
|
The secondary_reads_passthrough task on enterprise-rhel-62-64-bit-inmem runs 20 mongods (4 jobs with a 5 node cluster) and occasionally the host runs out of memory, leading to one of the mongod being killed. The task should be moved to run on a rhel62-large distro instead of a rhel62-small currently. |

Thanks for the clarification yves.duhem. Focusing on the amount of memory available for each resmoke.py job is a great point. We had to make similar decisions for |

max.hirschhorn, we still want to increase the instance size but, as robert.guo pointed out, the ratio of RAM to CPU is the same on the rhel62-large. So the ticket will also involve limiting the number of jobs the task will run on this build variant. |

cristopher.stauffer, yves.duhem, why don't we want to increase the instance size? My recollection from the linked BF ticket is that each mongod using ~500MB of memory which seems reasonable to me. |

Based on our conversation during story pointing, this should turn into a research ticket to identify the correct approach for resolving this issue. |
