I would start by limiting zfs arc cache maximum value inside global zone as well as in kernel zones to some sane value, depending on the workload.
Depending what you run in zones, might want to limit ZFS arc cache to couple of GB max (leave everything to service in question).
This will, of course, limit the read performance of a host (cache is smaller, less cache hits more physical reads).
Do you run everything on ZFS filesystems (applications, databases) or some other combination ?
