Don't be concerned with the yes, but after living some 2 years with this, i;m not so sure anymore. > fact it's a brand new machine, it happens there too. Could be a bad > memory chip, could be incorrectly set BIOS chipset timing parameters. maybe, but all the hardware here is 'industry standard' top shelf, high quality, i don;t have teh resources to be constantly replaceing bits as they fail .. i just by teh best and sit on teh warrenty queue if anything goes wrong. in teh 12 years i've been buy and using hardware i've only ever had two warrenty claims, both sort of my own fault. i suppose what i'm saying is that the hardware in question is not a junkbox recycled parts assembly. this is what makes teh whole situation so annoying. > If, on the other hand, you can find a reproducible situation, we > should take a look at the entrails. depends on what you mean by 'reproducable situation' while i cannot guraentee a particular session will core, if i;m runing xfree86 i know that someting will core sooner rether than latter. it is as if x has beome 'nervious'. about the only app that reliably will not run anymore is teh andrew port. it just cores, sig11 on startup and that is it. i've still got it on teh hard disk i'll dig it up and report back. part of teh resason i've embarked on this course, is that x11 is becoming teh 'way to fly' and i'm getting interested in web applications,as well as building an 'internet and web access' turnkey solution for disabled people with neurologically dsyfunctional fine motor control and legally poor eyesight. in short i have to make x11 work, and this means find out why all this happens, i cannot afford to throw more hardware at this problem. i mean i'd like a dec alpha and 500 mb dram, but nobody is going to give me one nor a hitachi 21 inch monitor .. so i make do with what i have. and, grumble about x11, grin. with thanks, regards jonathan -- =============================================================================== Jonathan Michaels PO Box 144, Rosebery, NSW 1445 Australia ===========================================================<jon@caamora.com.au> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
