Hi Pany, Those messages are normal (notice that they're INFO, not ERROR). This happens when ranges split and the writing clients METADATA cache gets stale. The client will re-scan the METADATA table to refresh its cache upon encountering these exceptions. This all happens transparently and your loading clients will handle them properly and re-submit any updates that were mis-directed.
