Public bug reported:

Binary package hint: libapache2-svn

I have a large Subversion repository hosted with read access over plain
HTTP. When checking out from the repository, the Apache process that is
serving the WebDAV REPORT request starts consuming more and more memory
until all memory and swap space is consumed and the machine becomes
inaccessible. The only work-around I have found is to set "ulimit -v
3000000" before launching Apache, which effectively kills the process
when virtual memory usage hits 3Gb. The client can then restart the
checkout and eventually it will be completed.

I have only noticed the leak when using Subversion clients, and tests
with Apache Bench don't seem to cause it, so it would appear to be a
problem with the Subversion module. I can't be absolutely certain at
this stage though.
