Hi All,

We are facing serious problem. We are not able to fire any command on the our HP-UX 11.11 server.
It display following message:
"/usr/bin/sh: The fork function failed. There is not enough memory available."

Hi

Before some time I executed the BDF command and found that no filesystem was full.

But now I am not able to execute a single command, not even bdf, uptime, w.

I am not able to telnet the server to take another terminal.

Looks to me like system resources full can please direct / Console login to the system

swapinfo -ta --> post the output
need to check kernel parameters like shared memory.

if your swap utilization does seem to hit 100%.

Create a logical volume (Make sure you have atleast 4 GB of space in any volume group)

Follow as example :-

#lvcreate -n swap -L 4000 vg01
Edit /etc/fstab and place the entry
/dev/vg01/swap ... swap pri=0 0 0
#swapon -a

#swapinfo -t

and make sure you have the swap listed.

It could be related to insufficient memory.

check
#swapinfo -tam

and

system process limit

#kmtune |grep maxuprc

Hi Johnson,

I tried Console login but also fails and showing following error
" PID 7508 received a SIGSEGV for stack growth failure. Possible causes : insufficient memory or swap spacw, or stak size exceeded maxsize."

But now I am able to extend the swap by 4GB.
and it works.

Now the system working properly

Thanks for quick support..
