Which SDE are you using ?
I’m using SDE 9.7.0 and did not see these errors …

Basically, operations_execute() sync counters tied to a table.
If you don’t yield this primitive counters belonging to tables are not
updated at all.

I tried to upgrade my WEDGE to 9.8.0 but it seems that I have the issues now …
I’ll get back to you as soon ass as I can solve this upgrade issue.
