WCF: The socket connection was aborted

CommunicationException was unhandled by user code
The socket connection was aborted. This could be caused by an error processing your message
or a receive timeout being exceeded by the remote host, or an underlying network resource
issue. Local socket timeout was '02:48:04.9840000'.

I've been testing this application for months and have just seen this error after making a small change to one of the services. It's only a few seconds, so I don't think it's a timeout issue.

InnerException: System.IO.IOException : The read operation failed, see inner exception

(Inner) InnerException: System.Net.Sockets.SocketException - An existing connection was forcibly closed by the remote host.

Any suggestions are greatly appreciated!

Thanks in advance

Solution

You are most likely running into quota issues like the MaxReceivedMessageSize, MaxArrayLength, MaxStringContentLength defined in the binding.

You can also have a look at the MaxItemsInObjectGraph attribute available in the behaviors.
