 +===== ZFS Logging =====
 + 
 +have an issue where ZFS consumes all available memory as a result of that same periodic 100.chksetuid script running. It normally grinds the machine to a halt but I think I've also had a panic.
 +
 +Could you set up a log of the zfs sysctls like:
 +Code:
 +
 +export ZFSLOG=/tmp/vfs_zfs.log; while true; do date >> $ZFSLOG; sysctl vfs.zfs >> $ZFSLOG; sleep 30; done
 +
 +and see what the vfs.zfs.arc_meta_used is before it crashes?
