My guess is that you need to increase the MaxKeepAliveRequests setting
in httpd.conf on the SVN server.

Once the MaxKeepAliveRequests limit is reached the server closes the
connection so the client opens a new one and authenticates again.

Serf-based clients send a lot more requests than Neon-based clients.
It seems the Neon-based clients do not trigger the limit in your
situations, while Serf-based clients do.
