           Summary: rsync timeouts and stays in state D

I'm syncing a rather big list of small files using rsync. My client is rsync
3.0.7-1ubuntu1 running on Ubuntu Lucid, and the server is a backport for rsync
3.0.0-1 for Debian 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.
