Are you using eval() quite often in your code? That's a big number.

It is normal to see lots of null:null references, especially for
nodes.
Using eval() too much can be a cause of node leaks. You can track
eval()
by using sourceline macros in your code:
eval("CODE", nil, __FILE__, __LINE__)

The rest of these counts look reasonable to me. For example, running
bleak house on an empty script that only requires rubygems and
bleak_house has, as its top output:
31778 __null__:__null__:__node__
23729 __null__:__null__:String
1945 __null__:__null__:Array
Without knowing more about your app (Rails server? Standalone script?
Daemon?) I can't direct you more specifically -- but if you're using
eval() (or a related function) then that's where I'd start. If you're
not using eval, then you may want to make sure you're reproducing the
leak while running in bleak house.
