It's difficult to tell from this error message, but does your server
require the use of client certificates?
IOW, do you have the 'ssl-client-cert-file' config set in your
~/.subversion/servers file?
If that's the case, you might run into an OpenSSL issue that's
triggered by serf (the http library svn uses). More details here:
https://code.google.com/p/serf/issues/detail?id=135 .
The error happens when a server requests a renegotiation (to ask for
your client certificate) while HTTP requests are waiting in its
in-buffer to be read.

If it's solved when restarting the server, then this would be a server
error, but I can't remember seeing such a problem mentioned on this
list. In any case it's interesting to see the apache access and error
logs at the time you're seeing this error message.
If my guess about the client certificates is right, you'll see this
error in the apache logs: "Re-negotiation handshake failed: Not
accepted by client!?"
To get more info in the server logs try logging with log level "trace8".
