Morning, I do not think that MAXUSERS > 128 is a problem at all anymore. I have two very high traffic/load public machines running 3.4-release and 3.4-stable, both have MAXUSERS set at 512 and even NMBCLUSTERS as high as 32,768 - I've never had a drop of trouble out of either of these machines. To be quite honest with you, I'm not very sure where this idea came from that MAXUSERS > 128 is bad, I've been running configs like that for quite a while (I guess ( 3.1+)) and never had a bit of trouble, minus the time I had a hard drive fail, but that doesn't really count =) Hope this helps, Matt -- Matt Heckaman [matt@arpa.mail.net|matt@relic.net] [Please do not send me] !Powered by FreeBSD/x86!
