I've been working on a multithreaded server using winsock for a MMORPG I'm designing. The server reaches somewhere around 90 connections (never the same limit), then it doesn't allow any more connections. The error the client receives from WSAGetLastError is 10055 which is: WSAENOBUFS No buffer space available. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. How do I adjust the size of this buffer/queue? Anybody? : ) Thanks, Balrin Edited by - Balrin on 8/12/00 3:45:07 PM
