I think most of us would consider that an eclipse bug, but yeah, until it's fixed it'd make sense to work around it.

Kinda similarly, I have a mostly identical setup on several machines, and on one of them Firefox has a memory leak, which even showed up just recently. It also seems to manifest if I have certain pages open, the most noticeable of which is Reddit.

It's the kind of stuff I could dig into, buuut it's just a PITA.
