You need to modify some kernel settings via /boot/loader.conf and reboot. Here's what we use on our production RELENG_6 and RELENG_7 boxes: # Increase maximum allocatable memory on a process to 2GB. # (We don't choose 3GB (our max RAM) since that would # exhaust all memory, and result in a kernel panic.) # Set default memory size as 768MB. # Maximum stack size is 256MB. # kern.maxdsiz="2048M" kern.dfldsiz="768M" kern.maxssiz="256MB" > I have also read that there are two sysctl namely, kern.maxdsiz and > kern.maxssiz, that can tune memory allocation but what happend to them in > Freebsd 6. These are not sysctls, they are kernel settings. They exist on both RELENG_6 and RELENG_7. -- | 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.
