My system would work fine as long as the expire would take a few minutes; but then something would happen and the expires would start taking 8 hours! And the system would soon crash; somtimes a hard lock up and sometimes with the same "page fault in Kernel mode" that you see. I finally figured it out...at least my system hasn't crashed for over a month. When expire is rebuilding the history file, it tries to fit the history.pag file in core. If it can't, expire resorts to using a disk file which is horribly inefficient and stresses the system something fierce...apparently enough to tickle a latent bug in FreeBSD that causes a subsequent crash. The solution, a common one for 2.2.5+ problems, is to edit /etc/login.conf; in particular the news entry. Here is what my entry now looks like: # # Settings used by news subsystem # news:\ :path=/usr/local/news/bin /bin /sbin /usr/bin /usr/sbin /usr/local/bin /usr/local/sbin:\ :cputime=infinity:\ :datasize=infinity:\ :datasize-cur=infinity:\ :stacksize=64M:\ :stacksize-cur=64M:\ :memorylocked=64M:\ :memoryuse=128M:\ :memoryuse-cur=128M:\ :filesize=infinity:\ :coredumpsize=infinity:\ :openfiles=512:\ :maxproc=128:\ :priority=0:\ :requirehome@:\ :umask=022:\ :tc=auth-root-defaults: Steve Grandi, National Optical Astronomy Observatories, Tucson, Arizona USA Internet: grandi@noao.edu Voice: +1 520 318-8228 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
