What does "Vector 0xdd(TMR)" do and how can I fix a problem that I'm having with it?
I have two other suggesting that also helped me fix issues that I was having. Both of them are pretty easy too (no need to mess with any system files or change plist or anything else like that).

1) Go to the Disk Utility app on your computer and press the buttons in following picture in the order that they are numbered. This will make OSX scan your hard disk and attempt to fix any potential file permission problems you may have. If this doesn't fix the memory issue, it should a least make your computer run a little smoother. I find that doing this one in a while really helps performance on my computer (which is fairly new by the way, so this helps even on relatively resent systems).

(PS. 1(b) is optional, most likely it will be grayed out anyway unless you run the Disk Utility app from Network Recovery Mode or while running off a separate hard drive.)



2) If you have antivirus installed on your Mac and you turned on the Scan Archives option, turn it off. The reason this feature is not on by default is that it affects the computer's performance a lot any time you run a local java program. It sounds like a really cool thing to have on, but it comes with a serious performance draw.

I'm not sure if this will help free up your RAM, but if nothing else helps, this is a quick and easy way to speed up your computer. :)
