I have almost the same setup (OS is Windows 2000).

If you have many files in a single directory, checking out the directory (or
doing an update that adds that directory) will lead to unconstrained memory
consumption. I think this is issue 773.

For example, I currently have a directory with over 1300 1k-4k text files.
Attempting to check out this directory leads apache to consume over 700MB of
memory, then fail. And of course, since we don't have resumable checkouts
yet, this means the repository cannot be successfully checked out at all
over http. Note that I have not been using properties *at all* in this
repository.

Solving either of these issues would let me live with the other one, but
having both is a major stumbling block.
That said, projects with more rational layouts will often not see these
issues since they will have far fewer files per directory.
