How are you updating the 8 records from the database? Is it being done directly on the server? Is it an actual region.put(key, JSONFormatter.format(newString))?
Is there any chance that the object in the cache is being modified underneath the index? I am not quite sure how the values were indexed properly and then now unable to be removed unless there is something occurring that is changing the value into an integer from a pdxstring.
