Good Day,
I have a tested flow that watches a mailbox and when a new email arrives, it parses the body of the email to JSON and send the data to Log Analytics in Azure. (These are system events coming from an application that does not support syslogging etc.) The problem I have is this mailbox receives a lot of email fast. ~1000 messages every hour minutes. In testing, everything works fine. Average processing time is maybe a few milli seconds to ~800 ms etc. However, after a few hours, the Flow engine stops processing. It seems like it hangs and stops working. (I have it set to only run 75 parallel flows.) I check and I see them in a running state for 18 hours or more. I have a premium licenses for everything so not sure if this is a problem with Microsoft or the flow engine can't handle the amount of email that I am trying to process. If anyone could point me in a direction to try and fix this, this would be great. Yesterday, I processed ~5000 emails. Today, everything stuck and the inbox has 19000 emails that have not been processed. Any idea how I can fix this?
Thanks,
Geo
