HP-UX 11i v3 Read Before Installing or Updating, September 2008 (Update 3 Release)

Known Problems
This section contains critical, late-breaking information that was not included
in the HP-UX 11i v3 Installation and Update Guide.
Before cold-installing or updating to HP-UX 11i v3, make sure you read this
entire section and “Appendix A, Known Problems and Troubleshooting,”
in the HP-UX 11i v3 Installation and Update Guide.
For information and patches for other known problems, go to the HP IT
Resource Center website:

After Installation, Applications Calling getpw*() or getgr*() Will
Dump Core in libc During a Certain Window
After cold installation, the pwgrd(1M) daemon creates the file /var/spool/
pwgr/status with zero size and initializes it with status information. There
is a small window between file creation and initialization in which file size
is zero. If any application calls getpw*() or getgr*() APIs during this
window, they will dump core in libc.
What To Do
Install PHCO_37620 to fix this problem. For availability of the patch, check
the HP IT Resource Center site: http://itrc.hp.com. The other workaround
is to rerun the applications/daemons that have failed by dumping core, or
reboot the system.
