Please check your rsync log file (created by the daemon) for
error messages.  Also try without compression.

It seems as though something happened in 2.5.6 where
compression and daemon produce this.  My impression is that
it doesn't happen via ssh nor without compression.  So far
we don't have a test case nor have any of the developers
experienced it.  You may want to try cvs where some of the
io routines have been changed.
