Every CP/CPP input link sets up a local CA monitor.
When you create a CA monitor, you get an initial update when the connection is made.
That initial update on CP/CPP input links processes the record (as CP/CPP means "process on every update").
Multiple CP/CPP input links (e.g., on a calc record) process the record multiple times. (!)

Using the disable mechanism is a possible workaround. Point all the records that you want to quiet down with their SDIS links to a single disable-after-boot control record, and have that control record enable the others after the CP/CPP links have connected - time-based (= after a little while) is the simplest way.

Cheers,
~Ralph
