[DeleGate-En] Re: Can memory usage be reduced?

Yes I have

I am currently running a pilot where people will be using several
delegate service processes running on an NT4 server. I got the shivers
after looking at the process list when this server is running for
several days, and after piloting a number of 80 people will be accessing
my server; the pilot users are only 10. So yes, I'd like to see this
forking new processes go away!
