As remarked in the other thread, the unique constraints for the table
nagios_servicechecks is missing causing duplicate rows. This patch
removes the KEY defines and adds an unique key just like
nagios_hostchecks has defined too.
As I am not sure in which file you will put the ALTER statements since
1.4b9 is out already, I'll attach those statements as is.

I've tested the patch and everything works fine now - no more duplicate
rows.
Kind regards,
Michael
