see exactly why it happens.

        I'm reluctant to use --ignore-errors because a few missed
deletions during an hour or so won't hurt much. However if there truly
is an error that is not triggered by the exclusion of cvs lock files
using --ignore-errors may cause annoying damages.

        Would you like me to change the frequency ? Every two hours
during peak time ? As far as I remember, if a rsync server is run
instead of an inetd launched rsync it caches the file list for a while.

        I did this thanks.
