They definitly do not swap. I've just removed swap space... ;)

Of course, I know that formula. MEMnom is around 600k, so if we
calculate a bit generous:
(1024MB - 3MB - 64MB) / 1MB =  957.

MaxClients is at 300... 


Dead end on this way, I think, but I thank you for your effort!


Still helpless,
Jan
