When using the new Check_MK rrd format (single value per RRD), the host rename feature was not renaming host specific entries in the journal of the rrdcached.

This resulted in lost RRD values that have not been written to the RRDs yet.

Manual fix: You could stop the rrdcached (or the whole site), go to var/rrdcached and rename the host in the journal files manually, e.g. using sed.
