Hi,
As for 9800 entries instead of 10000 - most possible that you just have
a small mistake when you work with your counter and these entries were not
written to the DB: if(counter==100)
Anyway, for both problems community need additional information for an
investigation. It would be great if you could share your full project with
all configs and code, so the community can fast reproduce your issue and
help you.
