4764193 xfs crashes on bad request

Patch Installation Instructions:
-------------------------------- 
Refer to the man pages for instructions on using 'patchadd' and 'patchrm'
scripts provided with Solaris.  Any other special or non-generic
installation instructions should be described below as special
instructions.  The following example installs a patch to a standalone
machine:
 
	example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
	example# patchrm 104945-02
 
For additional examples please see the appropriate man pages.

Special Install Instructions:
----------------------------- 
 
The X Window System Font Server, xfs, is normally started automatically
from inetd on Solaris when a request for a font service is received.
Therefore, to protect a running system against bug 4764193, after
installing this patch, you must either reboot or stop all running xfs
instances.  Xsun clients using the font server will detect the font
server shutdown and reconnect automatically to a new instance of the
font server. Unfortunately, some other font clients, such as some
versions of Xvnc, will not reconnect automatically and will need to be
stopped before killing the font server and restarted again after the
font server is restarted.  (If xfs is still being run from inetd, inetd
will automatically restart on the first connection attempt.)
 
To kill the font server, as root, run the command:
 
pkill -x xfs
