Pls also reply to me as I cannot subscribe to the list @this time. Thanx much to any repondents in advance. I need to run large address space jobs using FreeBSD 4.3 I have already upp'ed the available space to about 1.5GB (6 * 256MB). But that was not enough and now I would like to go to at least 2GB or perhaps 2.5GB At present time we have the following params in the kernel config; MAXDSIZ="(1024*1024*6*256)" DFLDSIZ="(1024*1024*6*256)" Also kernel has been slimmed down to exclude any and all unnecessary devices and parameters we are not using. We have a machine which is 1.5GB mem running at 1.4GHz (AMD Athlon) we have 6 others which are .5GB each running at 1.4GHz as well. All run FBSD4.3 So far we're very pleased w/ stability and perf. None require X, all run just in console mode Can you help me understand what I need to do. I am an experienced programmer and this is quite important to me. My application does not require any graphics or X support. we haven't installed X on any machines even as it's not needed. All I need to do is issue many large mallocs'. (Seems so simple, doesn't it.) __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!
