When running the pack through PolyMC 1.4.1, within an hour my ram usage doubles (8gb) what I allocate to the game (4gb), and continues to rise gradually past that until possibly peaking at a triple (12gb) of the allocated amount; if more info is needed I can provide it.

having a similar issue useing 0.4.29. is also causing a massive slowdown of entire system

Same. Since 0.4.23, I've had bad RAM issues. Prior to that, I was sitting at about 6-6.5 gigs. From 0.4.23 till 0.4.28, it started at 8 gigs and went beyond within minutes, rendering the game unplayable. As of 0.4.29, it starts at 8 gigs and becomes very stutter-y within half an hour.

Happy to provide any information that may help diagnose the issue.
