If streams you can use netstat to see if you are overrunning a kernel parameter, you can do it with sockets as well but I can't remember how. Have you got enough PCB's allocated to cope with the number of inbound connections? If you have a lot connections arriving at the same time check the q-exceed on the onstat -g nt? command. Nobody at ITS seemed to know what it meant when I was last chatting to them but if you see it increasing quickly then you need to add another listener-thread to the engine. -- Paul Watson # WF Software Ltd # It said run using Windows 95 Tel: +44 1436 674629 # or better in the manual Fax: +44 1436 678693 # so I used Unix www.wfsoftware.co.uk #
