I've seen something similar to this on 5.3 and 5.3-STABLE buildworld it happens on fast machines (both SMP & UP) when running 'make -j n buildworld' with n larger than about 8. It does not happen everytime, just often enough to make you wonder if the hardware is flaky or not. I have seen this on P4E (Prescott), Xeon (533FSB & 800FSB) as well as SMP Opterons. I can't remember getting it on the Celerons. If anybody wants patches that fixes this tested, I'd be happy to help. It is very annoying when using buildworld to see if a newly built machine is working OK. -- Martin Nilsson, CTO & Founder, Mullet Scandinavia AB, Malmö, SWEDEN E-mail: martin@mullet.se, Phone: +46-(0)708-606170, Web: www.mullet.se Our business is well engineered servers optimised for FreeBSD & Linux
