Thanks for the info.

In mentioned example apache runs on worker mpm. I've sent a message to this
group few days ago about users experience with svn and worker mpm. I didn't
get any answer. It concerns me if svn is thread-safe and if the said memory
problem would appear on prefork mpm. I will be doing some tests this week.
