hi,
page fault occurs when a process tries to access memory that is out of it's limit or
the memory that is not present. A software
can cause this if it tries to acccess the
system memory.
As a matter of routine , check your memory usage and swap usage , log a call to HP and
get the hardware certified.

Its simply a data page fault - basically the kernel panic'ed and crashed when it shouldnt have. Simply a patch issue. Your patches arent up to date. Load the latest patch bundle (March2002) or if you just want some individual patches go to the itrc home page, select individual patches, do a search for 'data page fault' for your HP-UX version and it will list the patches you should install to fix it.

We had the same problem here recently - March2002 patch bundle install fixed it.

First of all I think only HP response center would know how to direct this stack trace to an expert to translate what it meant. It's not an easy thing to understand. At the end of the day it is usually going to be patch installation that will solve your problem. I have ha similar crash, stack trace not quite the same but the "attachment" looks very similar to mine when it happened. I was told to install ..
PHNE_21038 cumulative ARPA transport patch
which should resolve the "race conditions" that are seen in the stack trace. And that I did and I never had the crash again.

I would advise to contact your local Response Center which would most likely like to have the deum-files sendt in for analyzing.

Hi,

I would check as well as HP as the guys from checkpoint FW.
If no contract I would suggest you started with installing the latest Arpa and streams patches and the dependencies.

I believe this is fixed in PHNE_19375, superseded by PHNE_26771.
Do not forget the dependencies!
