Apache Error after installing VisualSVN Server - Too many errors in select loop.

Hi there,
I have installed VisualSVN Server v2.1.1 on our 2003 Small Business Server so that we can store our development code and have it backed up regularly.

While I seem to be able to intall it fine on all of our development PC's, it will not run correctly on our 2003 server.

The install goes through fine, the Visual SVN Server starts ok but when you browse to the URL all you get is a blank screen.

Looking through the even viewer I found the following event in the VisualSVN Server event log :


Event Type:      Error
Event Source:      VisualSVN Server 2.1
Event Category:      Apache
Event ID:      1002
Date:            17/04/2010
Time:            1:39:43 p.m.
User:            N/A
Computer:      ServerName
Description:
Too many errors in select loop. Child process exiting.
(OS 10038) An operation was attempted on something that is not a socket.


I have read all sorts of things about this problem on the internet but nothing that I have tried has seemed to work.

The VisualSVN service is set to run with the "Network Service".

I have verified the permissions on the VisualSVN installation folder as well as the repositories folder.  I even granted it full permission to these folders to see if that would help.

I have it set up to run on it's one IP address.

I have tried running on different ports. 8080, 443, 9000, 9090

I have disabled the antivirus on the server.

I have stopped the IIS service.

Nothing has seemed to work.

I have included the httpd.conf file that VisualSVN generates in case that helps.  It is worth nothing that the included "httpd-custom.conf" file referred to at the end of the file is empty.

Does anyone have any experience with this issue or could help point me in the right direction?
