The difference was that I could reproduce the problem every 4 to 12 hours while crunching large numerical codes in 8M core with 64M swap. Eventually recompiled with the kernel debugger so at least the system froze with a death message. Never saw it die with the same task running, or same address, or interupt mask, or nothing. Error was always the same, "Segmentation Violation in Kernel Space" (signal 12?) or some such. Reverting to 2.0.5R seems to have solved my problems. Stange that another similar system had no problems at all, same task, same FreeBSD. I partly suspect the motherboard. -- David Kelly N4HHE, n4hhe@amsat.org, dkelly@iquest.com ============================================================= The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
