Try tuning memory parameters via loader.conf: $ cat /boot/loader.conf # Increase maximum allocatable memory on a process to 768MB. # We don't choose 2GB (our amount of RAM) since that would # exhaust all memory, and result in a kernel panic. Maximum # stack size is still set to 128MB. One can view these # settings using limits(1). # kern.maxdsiz="805306368" kern.dfldsiz="805306368" kern.maxssiz="134217728" Adjusting kern.maxfiles and kern.maxfilesperproc might also help. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
