If you can provide your run parameters, Ola (like what gem you're installing and any uncommitted patches I'd need) I can bump the heap up to 2G on my machine here and see if it still fails. In my opinion, if it's anything over 128M there's a bug somewhere leaking memory.

Did you try raising heap options in Java? Hardly a nice solution, but
it would be nice to know the upper boounds on memory. The other thought
could be a memory leak? Who knows...maybe we are holding a reference somewhere
and not releasing something?
The JYaml thread does seem like a more long-term solution, but it would
be nice to figure out if this is a leak or not.
