memory issues with wm6.1

[holo]

so everyone is posting about how well WM6.1 handles memory management - opening apps when you are completely out of ram and all that....

For me, however, it will not, stuff will randomly start to close when I run out of ram (and after running for 24 hrs with only a few apps added - sbp pocket plus, and phoneweaver mainly, I'm down to like 8 megs of ram with nothing open)... What gives? Am I missing something? I can't even load big web pages in IE anymore with NOTHING open..... (or play youtube vids/etc)...

edit: running no2chem 5038 (I think that is the build - not really sure but around there anyways)...
