Thanks Roy Any ideas how to code this child process stuff, as I said I am newbie and not from a coding background to be honest ideally yes, i'd get 50K, but if i can get above 30K that would be OK Alan "Roy Smith" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > In article <[EMA

Thanks for the feedback. Using the socket in a list is great However, as i imagined, I now get a limit of around 1500 conns before the system crashes out, also i have noticed, that the ports loop back to 1025 when they hit 5000. Any ideas on how to make the list/socket get to around 50K TIA
