The ZFS file system is known to use nearly all available RAM as
cache if the default system settings are not changed. This may
lead to a heavy fragmentation of the host memory preventing
Oracle VM VirtualBox VMs from being started. We recommend to limit the
ZFS cache by adding the following line to
/etc/system
, where
xxxx
bytes is the amount of memory
usable for the ZFS cache.
set zfs:zfs_arc_max = xxxx
