Possible to decrease RAM quota?

Thanks for the reply. I should have been more detailed. That seems to work
only when the current RAM usage is below the intended level. I was looking
for a way to effectively truncate the cache via something like LRU. For
instance I’ve got the current quota set to 12GB, usage is 9GB but I would
like to try 6GB. When I do that now, I get a message saying “RAM quota
cannot be set below current usage.”

Thanks again
