Public bug reported:
Binary package hint: rsync
I'm syncing a rather big list of small files using rsync. My client is
rsync 3.0.7-1ubuntu1 running on Lucid, and the server is a backport for
rsync 3.0.0-1 for Etch (although I had the same problem with rsync 2.6.9
as server, so it seems to be a problem on the client side).
Some time in the middle of the sync, the client freezes. When I kill it
(using ctrl+C or kill), the client returns with an error "undefined
error" but the process keeps running in state D (as seen in ps), so it
cannot be killed. The servers returns, too, and is not seen anymore in
the process list.
Here are the last lines of the strace tracks on both the client and the
server:

I can't find where this problem comes from, but I get it every time I
relaunch rsync.
