Posting Message to EventHub from External System

Question

Hi Team,

when someone is posting to the event hub which I configured, below is the error message which I'm getting which I captured in the monitor.

What could be cause of the issue? anything to do with ASP Plans/ Resource Groups / Any limit exceeded. The reason for the Ask is the eventhub is used by Multiple consumer groups and also might be the request might be receiving from multiple systems too.

"An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full."

Hi Suchai Tammewar ,

Thankyou for using Microsoft Q&A platform and thanks for posting your query here.

It could be port exhaustion. When application makes too many outgoing connections in short time frame or does not dispose outgoing connections properly - you run out of ports.

You may receive this error when you try to connect from TCP ports greater than 5000

Kindly check the details on socket limits: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

Hope it helps. Thankyou
