Title:
  Apache mod_dav_svn leaking memory

Status in Subversion:
  Confirmed
Status in “subversion” package in Ubuntu:
  Confirmed

Bug description:
  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.
