To whom it may concern,
I'm currently researching using Oak in conjunction with Mongo for a scalable
content repository. I've done a proof of concept without any issues but now
that I'm running some tests I keep coming upon a problem. Below is exception I
keep getting. This happens when the number of files is over 100k.
Exception in thread "main"
