Subject: Default value to field SCAN

Hi,

When I create records and don't set the field SCAN, what is the default value? There is an way to change this?

I'm having problems with a set of records without SCAN field that are consuming a lot of CPU, and receiving this messages:

dbScan warning from '.2 second' scan thread:
        Scan processing averages 0,00 seconds (0,00 .. 0,02).
        Over-runs have now happened 283681 times in a row.
        To fix this, move some records to a slower scan rate.

dbScan warning from '.5 second' scan thread:
        Scan processing averages 0,00 seconds (0,00 .. 0,03).
        Over-runs have now happened 290049 times in a row.
        To fix this, move some records to a slower scan rate.

dbScan warning from '.1 second' scan thread:
        Scan processing averages 0,00 seconds (0,00 .. 0,03).
        Over-runs have now happened 278431 times in a row.
        To fix this, move some records to a slower scan rate.


If i remove small choices from dbd file (.1, .2 and .5 seconds) solves the problem. Apparently the records are being created with all SCAN values...some idea to solve this?

Regards,
