Several different interpretations of WinSock error number: 10053 wsaeconnaborted

Partial excerpt:

Berkeley description: A connection abort was caused internal to your host machine. The software caused a connection abort because there is no space on the socket's queue and the socket cannot receive further connections.

Winsock description: Partly the same as Berkeley. The error can occur when the local network system aborts a connection. This wowould occur if Winsock aborts an established connection after data retransmission fails (handler never acknowledges data
Sent on a datastream socket ).

TCP/IP scenario: A connection will timeout if the local system doesn't receive an (ACK) nowledgement for data sent. it wocould also timeout if a (FIN) ish TCP packet is not ack 'd (and even if the fin is ack 'd, it will eventually timeout if a fin is not
Returned ).
