HP-UX 11i v3 Installation and Update Guide, September 2007 (Update 1 Release)

Table A-1 Known Install and Update Problems (continued)
Description/ActionProblem
Critical Resource Analysis (CRA) may unexpectedly fail during
Online Replacement (OLR), Online Deletion (OLD), or dynamic
unload of a Fibre Channel driver module. OLR occurs when doing
a replacement operation with either the olrad command, PCI
attention button, or the Systems Management Homepage (SMH) on
systems with this OLR feature. OLD occurs when doing a delete
operation with the olrad command, or the Systems Management
Homepage (SMH) on systems with this OLD feature. A dynamic
unload of a module can occur with kcmodule, swinstall, or
swremove commands.
OLR, OLD, or dynamic unload of a DLKM capable Mass Storage
driver, might unexpectedly fail during Critical Resource Analysis
(CRA) causing a core dump. If the CRA fails in this way during a
swinstall or swremove operation the system will automatically
reboot to complete the requested operation. If the CRA fails during
a kcmodule mod=unused operation, the unload action will not
occur until the system is manually rebooted.
What To Do
Install PHCO_36356 to fix this problem. For availability of the patch,
please check the HP IT Resource Center site: http://itrc.hp.com.

Single-threaded applications linked with libpthread shows
performance degradation because of thread safe libraries having to
acquire and release mutex locks.
What To Do
Install patch PHCO_36551. The new libpthread patch PHCO_36551
reduces the overhead of calling pthread_mutex_lock(3T) and
pthread_mutex_unlock(3T) in a single threaded application.
