Out of memory

[Coste Nicolas]

Hello !! I wish to run a CFD commercial code on our
station (4GB Ram - HP-UX 10.2).
But each time I run a big job I receive :
out of memory or could not allocate storage.
I've seen that I should increase certain kernel parameters but I don't know
them.
I've tried to increase maxdsize but after reboot I've got error like fork : two
many processes ...
and can't do nothing, except reboot in single user and booting with old kernel.
Is there a way to allocate memory for a specific job without modifying the
kernel.
I've also read that up to 2.75GB there was problem.
Should I upgrade to HP-UX 11 ??
Thanks for advance

you could be out of swap space.
type in swapinfo -a . Is there any available.
There is a parameter in the kernel that can allow
the physical memory to bypass the swap space

swapmem_on

ALso, you must make sure that both maxssiz and shmmax are increased along with
any other parameteres

It works !!
I've turned on swapmem and used the parameter
provided in Tuning and performance of the HP doc !!
Thank's
