System Crashes or Panics
When Mux Cards are added to a computer system, the number of ports
and processes increase. Because of the increase in work load, system
kernel parameters may need to be changed.
Fine tuning your kernel is site-dependent. It depends on the number of
users on your system, what applications they are running and your
computer’s hardware configuration. Again, consult your system
administration manuals.
This is a complex subject and the answer is going to be different for
different sites. Rules of thumb, like doubling or tripling all relevant
kernel parameters, while they may get your system up and running, are
not the best solution.
Refer to your system administration manuals for information on how to
change the HP-UX kernel parameters.
