Can you provide more details? Because i didn't encounter such problems. Was this 500 MB in top was RSS ? What you describe should not happen, did you report a bug?

They were more like things the go runtime was doing but which I had no clue or information about, rather than bugs. The top info was indeed rss.

For me it seems like you probably leaked gorutines/not closed os resources or you encapsulated some data structures in themselves which then can't be garbage collected. It really looks like memory leak caused by app logic. But as i said you should report this if you are certain that is Go bug.
