+++ This bug was initially created as a clone of Bug #1558672 +++
In the bug this was cloned from we found that on large inventories memory consumption was larger than expected. We've calculated that the highest expected memory use would be 615MiB per inventory host so we're adding a check to alert users if their control host doesn't meet those requirements.
We expect the underlying issue to be fixed in the near future at which time we'll remove this check or reset it to the new threshold.
