The total storage size for all of the caches in the zFS address space must be less than 2 GB. zFS terminates when it cannot obtain all the storage it needs for the caches specified in IOEFSPRM file. In addition to the zFS address space caches, storage is necessary for processing file requests and for the products zFS might use. As a result, you must restrict the total zFS address space cache storage to approximately 1.5 GB. Use modify zfs,query,storage to determine the total allocated zFS storage. See STOR for more information about determining how much of the available zFS address space storage is being used by the zFS caches.

You might see messages IOEZ00188A, IOEZ00662I, or IOEZ00663I, which indicate that the zFS address space is low on storage. If it continues to be a problem, consider using zfsadm config to dynamically decrease the metadata, transaction, and vnode cache sizes.
