Our Windows Apache 2.0.59/svn 1.4.6 crashes seemed to be reduced by
adding this to the httpd.conf:

  MaxMemFree 512

http://httpd.apache.org/docs/2.0/mod/mpm_common.html#maxmemfree

We also turned off https:// access which could have helped too...

Our windows servers have never been as stable as our Solaris
servers, and the Solaris servers get at least 10x the svn
traffic (~40 svn requests/sec).
