Error lock file could not read status line

Hi,

We are thinking to upgrade our SVN repository from 1.6.6 to 1.6.21.

Before doing it, we are doing some functional tests. During these tests we
have realised that our integration "PB 12.5.2 + SVNSCC Push Ok 1.6.17" with
"SVN 1.6.21" is not working properly.

In fact, we obtain an error when we do a checkout with the "Reserved
checkout mode" activated in SVN Options.
The error obtained is: "Com.SvnClient.Error, HRESULT=... LOCK of 'path of
the resource to lock' Could not read status line: Se ha forzado la
interrupción de una conexión existente por el host remoto. (URL of our SVN
repository)".

We need to fix that error due to the need to update the SVN repository.

Any ideas to fix it or work around will be welcome!

Thanks in advance,

Regards.
