Argh, sorry, I read the docs for the wrong one, sorry for the misleading response. Carl Eastlund -- WARNING!

Same problem. The execution takes at least 20 seconds to get to 15GiB, so it can't be just that GC isn't running in order for the custodian to notice the usage over the limit. -Ian ----- Original Message ----- From: "Carl Eastlund" <<a href="mailto:carl.eastlund@gmail.com">carl.eastlund@gmail.com</a>> To: "J.
