I suspect you run into the LRU purging (and it sounds like it has a bug).

You don't say if your 30GB is 30M 1k objects or 3M 10k object, but
you need to be aware that there is a per-object overhead (you can
trim this somewhat down with the obj_workspace paramter), so 50GB
may not be enough to hold 30GB of objects.

Never attribute to malice what can adequately be explained by incompetence.
