I am hosting an Azure Event Hub and another company is trying to send messages to my Event Hub (via NodeJS). Most of the Time this works perfectly, however, sometimes (appearently totally random) they receive an ECONNRESET error. In my Event Hub, there are no logs or metrics indicating that there was some kind of error. I am in the basic plan for Event Hub, but the Limits of 1 MB/s or 1000 messages/s are not exceeded according to the metrics (max of 200-300 messages and 200 kb per 15 minutes). Authentication method is SAS.
Two things that are a little suspiscious in the metrics:
- Request count around 1.4 to 1.8 k per 15 minutes
- Size between 70 and 100 MB However, I wasn't able to find any information on limitations on these two metrics.
I wasn't able to find any information via Google about this specific error in combination with Event Hub. My partner company tells me, that it's an server (= Event Hub) issue, since they are only the client receiving the error but I cannot find any indication for problems on my side. Unfortunately I do not have any access to the code they are using.
I would be very grateful if someone could help me out.
Best regards Monika
