I used to see panics until I made the following additions: /boot/loader.conf vfs.zfs.zil_disable="1" vm.kmem_size="536870912" vfs.zfs.arc_max="67108865" /etc/sysctl.conf kern.maxvnodes=74500 [was 100000] The worst I've hammered the system recently was to ``rm -rf /usr/src'' (UFS) and then cvsup it from the local CVS repository (ZFS). --- Gary Jennejohn / garyjATjennejohnDOTorg gjATfreebsdDOTorg garyjATdenxDOTde
