I didn't see this mentioned in any of the follow-ups at the time, but
if svnsync is using Apache httpd using HTTPS, you are very likely
running into the SSLSessionCacheTimeout:

    http://httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslsessioncachetimeout

In essence, if a WebDAV transaction running over HTTPS takes longer
than the SSLSessionCacheTimeout value, it will fail.

The default SSLSessionCacheTimeout value as shipped by many Linux
distros is 300 (5 minutes), which is not nearly long enough for large
commits of binary data (especially over slower links).
