Denial of service using SVNServe on WinXp

From: Ayende Rahien <ayende_at_gmail.com>

Here is the scenario, I've a WinXP Pro computer that I used to run SVN &
CruiseControl.Net. I started to get a lot of broken build emails, all of
them pointing the blame to SVN connectivity (the message was: "the target
machine actively refused the connection"). The CC.Net & SVN are on the same

After investigating a little bit, I found out that after a while, it seems
that all attempts to connect to the svnserve (which is running as a service
using svnservice) failed. Trying to test that, I wrote the following batch


@echo off

set /a Count = 1


echo Trying for the #%Count%

Set /A Count=%Count%+1

svn log -v -r "{2005-04-29T17:03:05Z}:{2005-05-01T06:30:16Z}" --xml
--non-interactive svn://localhost/nqa/ > recent%Count%.txt

if errorlevel = 1 goto exit

goto start



I run this thingie, and at iteration 1200 - 1500, I get a machine shutdown!

I mean a hard shutdown, the kind where you need to push the power button to


I've no idea what is causing this, but I'm able to reproduce it reliably.

There is nothing else that runs on this machine, btw.


Any ideas ??
