I am facing some weird issue with Azure function and service bus trigger. Setup: I have 1 service bus queue (with session enabled) which has max. delivery count of 1 as shown below:- ![229990-image.png][1] I have an Azure function which gets triggered by a message in service bus queue. The function is combining multiple excel files into 1. But when I run a large number of files, the function seems to br running multiple times as shown in the logs:- ![230083-image.png][2] Earlier I thought that the message lock is getting released but I have already set the maxAutoRenewDuration to 1 hour (The function is using Premium plan). So I tested by simply adding a delay of 12 minutes and it's working as expected:- ![230102-image.png][3] Could you let me know why it's happening? Is the function crashing due to memory or something, if yes, why I am not getting any error message?
