Have you tried with one of the server demos included with ICS ? Just to see if it is related to your code or elsewhere.
It is also possible that windows run out of other kind of resource. Have you "instrumented" your program with - for example - FastMM which could tell you about memory leaks ? Another possibility is that you are wrongly handling some exception for example by simply shutting the exception down with en empty except block in a try/except. -- [EMAIL PROTECTED] Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be ----- Original Message ----- From: "Edward Koo" <[EMAIL PROTECTED]> To: <twsocket@elists.org>; <[EMAIL PROTECTED]> Sent: Thursday, September 13, 2007 5:33 AM Subject: [twsocket] TWSocket Stop Listening After Certain Numbers ofConnected Clients. > Hi Wilfried, thank you for replying. > > How do i check how much non pageable ram is available? > The test i did for Windows Server 2003 runs on a > system with Xeon processor and 3gb ram.
