Crash in libapr using apache

Hello I have a server running subversion and I found that it crashes once in a while (several times a day). OS: Windows 2003 SP1 with all recent patches. Apache: 2.2.8 without ssl (binaries from apache.org) Subversion: 1.4.6 (official build for apache 2.2) I don't know how to reproduce this problem, but I do get random crashes. Anyone saw this? Maybe I didn't install something properly? Maybe I can help by running some other diagnostic? I have a minidump of that crash if it can help more. Thanks!
