RESOLUTION
HP has made patches and product updates available to resolve the
issue. After installing the recommended patches for B.11.00, B.11.04,
and B.11.11 a system parameter must be set. A utility, sqmax, must
be downloaded and installed to set the required system parameter as
discussed below.
B.11.00 install PHNE_33395 or subsequent,
then install sqmax as discussed below
B.11.04 install PHNE_33427 or subsequent,
then install sqmax as discussed below
B.11.11 install PHNE_31091 or subsequent,
then install sqmax as discussed below
B.11.23 install PHKL_31500 or subsequent,
sqmax not required
The patches are available from http://itrc.hp.com
For B.11.00, B.11.04, and B.11.11:
->After the patches listed above are installed an internal system parameter
->must be set. A utility, sqmax, has been provided to set the parameter.
->The parameter must be set whenever the system is rebooted.
->An initialization file (sqmax.init.d) is included with the sqmax utility.
->The instructions in sqmax.readme show how in install the initialization file
->so that the system parameter is set automatically when the system is
rebooted.
The sqmax utility is available via ftp:

Login: sqmax
Password: sqmax
FTP Access:
ftp://sqmax:sqmax@xxxxxxxxxxxxxxxxxxxx/
or:
ftp://sqmax:sqmax@xxxxxxxxxxxxxx/
1. Download sqmax.tar from the ftp site into a secure directory.

5. ->After installing sqmax, run "/usr/contrib/bin/sqmax 1000".
6. ->As discussed in sqmax.readme, "/usr/contrib/bin/sqmax 1000"
->can be run automatically when the system is rebooted.
->The version of sqmax cited in rev.1 of this Security Bulletin will exit with
->a failure message when executed on a B.11.04 system. A new version has
->been provided which functions correctly on B.11.00, B.11.04, and B.11.11.
->The previous version functions correctly on B.11.00 and B.11.11. There is
->no need to download the new version for B.11.00 and B.11.11 systems.
->The new sqmax has the following what(1) string:
$Revision: 92453-07 linker linker crt0.o B.11.33 020605 $
sqmax: $Revision: 3.0 $ $Date: 07/17/2006 WTEC TSO Supported - MW $
