@Wouter Dumon Thanks for reaching out.
This is the Throttling Limits for the Frequency of trigger polls i.e. 1 call renewal period of 60 sec as documented here.
So max you have one call every minute. As you have specified the interval as 5 sec so the throttling call limit will be hit.
Unfortunately, you cannot have the trigger frequency of azure queue connector less than 1 minute.
Let me know if you have any queries or concerns.
