           Summary: synchronization failed
           Product: rsync
           Version: 3.0.8
          Platform: x64
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: mark at overmeer.net
         QAContact: rsync-qa at samba.org


After months of flawless mirroring, the rsync daemon process stopped working.
Some files get downloaded but at the end removed with "failed verification --
update discarded (will try again)"

The problems showed-up when I was running a 3.0.2-3.0.7 connection, but
is still present with 3.0.8 on both sides (which is used below). The files are
a few hundred megabytes each and do not change nor have disk read errors. Some
files work, some don't... it might be something related to a pattern within the
file or the filename.

Running the process with -vvv shows this:

I hope this is sufficient information to find the cause.
