If the patch above fixes your problem, then no need to post the strace. I'll just commit this patch.

commit 2a2c8e8c1fabd0a7515fdd728c0bb921381c1b37

    [affile] fixed 100% CPU usage for file sources (fixes: pub#43)

    The patch 8f7098563a1cc53220cd35c9dc415a11be502feb enables multi-read for
    regular files but as it seems this broke the EOF handling logic in
    LogReader, which is fixed by this patch.
