Hello Jeff,

The files must be locked from a previous SVN update.  I would recommend that 
you add the cleanCopy tag to your sourcecontrol block for each project.

    <sourcecontrol type="svn">
       <cleanCopy>True</cleanCopy>
    </sourcecontrol>

Thank you
Thon Becker

Subject: [ccnet-user] Connectivity issues - "existing connection was forcibly 
closed by the remote host"

I am having trouble diagnosing this error message. I'm not sure if it
is a problem with SVN, CCNET, the network, or the SVN machine.

*****

I have a few dozen builds set up on ccnet. ccnet pulls the source from
svn. A few times an hour, I get the above error message on my interval
triggered builds. A few times an hour means that most of the time, the
interval is working and getting a response. Indeed, I often see builds
starting and completing while watching the dashboard. But for some
reason, all repos seem to error out every hour or so.

Has anyone else run into this? Any idea what could be causing it? Our
network guy say the traffic looks fine and there isnt a problem with
the network dropping out. I see nothing in the server logs of either
the svn server or the ccnet server.

Next, I am going to try upgrading to the lastest version of SVN and
testing a repo on https:// instead of svn://
