Currently, all replica set passthroughs run on large distros on the ! Enterprise RHEL variant. Large distros typically correspond to 30GB of memory, while small distros correspond to 7.5GB.

The replica_set_reconfig_jscore_passthrough has been prone to OOM failures lately, killing mongod and python (evergreen) processes. This is a passthrough that runs against a 5 node replica set, which can sometimes take up most of the 7.5GB of memory, leaving little room for much else.

If the current replica sets passthrough (which usually have 2-3 nodes) run against a large distro, the reconfig passthroughs certainly should.
