Symptoms:
	PHCO_18133:
	The restore command core dumps when restoring a dump of a
	file system with a large number of inodes.

Defect Description:
	PHCO_18133:
	When restoring a dump of a file system with a very large
	number of inodes, the restore command core dumps while
	attempting to extract the inode map.  The software defect
	begins to be a problem when the maximum number of inodes
	for a file system is approximately 4 million, though it
	does not core dump and may not have any other visible
	adverse affects.  When the maximum number of inodes for a
	file system reaches approximately 8 million, the command
	dumps core.

	Resolution:
	When extracting the inode map, the code was using the
	s_spcl.c_addr[] array when reading in blocks of the map.
	The s_spcl.c_addr[] array has a size of 512.  If the map
	was larger than 512 blocks, restore would write beyond
	s_spcl.c_addr[512].  The new code defines a new "c_addr"
	variable which is dynamically allocated for the map
	extraction.

Installation Instructions:

	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHCO_18133

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_18133.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHCO_18133.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHCO_18133.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHCO_18133.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHCO_18133.depot of=/dev/rmt/0m bs=2k
