As far as I can see, that's a client side error, meaning that this is
a problem with Neon not being able to allocate more memory, or openssl
(against which neon is linked for SSL support).

Maybe Neon or svnsync forgets to deallocate some resource? It would be
great if you or someone else could try to find out. (How? Using
valgrind or pool-debugging?)

It's the machine on which svnsync is running.

I think it's safe to restart from where it left off. Does that work?
