Description Graeme Gillies 2016-09-21 22:15:38 UTC 
Hi,

A default RHOS 7 installation by director does not impose any limits on how much memory mongod can use. While this is perfectly normal for how mongod is expected to work, I think practically we need to introduce some kind of "safety" memory limit just in case. While mongod is supposed to be a good citizen and release memory when needed, it would be great to leverage the operating system to keep it in check "just in case".

Regards,

Graeme
