svn connection issue

We have around 20 subversion repositories setup on our fisheye instance. When we restart the application however, none of the repositories come back online. All show this error:

When I go into one of the repos and try "Test connection" it fails
,however if I change the username for the svn conneciton.....it passes; and then strangely enough, all the repos suddenly start working....with the previous username !

So it seems that with the username that was in use during the restart it will not work until a test is performed with another username?!
