I have an IoTHub and a Function app containing a function (EventHubTrigger C#).
I can see that the IoTHub receives approx. 6 messages from my device per hour - and the function gets called and stores data in a database. The function calls execution time is between 15ms and 60ms. (Actually 15-60ms is during test, now that i look closer to the call log it tends more to be around 70-140ms)
My problem is that the function stops getting called after some time. This has happened a couple of times now. Today, it ran for approx. 10 hours and then the function does not get called anymore. Messages are still received in the IoThub.
I can invoke the function manually with test data, and that is handled correctly. But it is still not being called from the IoTHub.
The plan i am running is Pay As You Go - NorthEuropePlan (Consumption).
Any suggestions ?
