Experimental Physics and Industrial Control System
Those dbScan warnings are very unusual. It makes me think there is something wrong with the timer system, because, for example the 0.5 second scan thread appears to be running much faster than 0.5 seconds, since it is averaging 0.00 seconds. What operating system is this?

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,
