Hi Markus,

Thank you for the reply. 
These are the output of "gm start" and "gm stop".

>[root@hgt001 root]# service gm stop
>Stopping gm... /etc/init.d/gm: kill: (13599) - No such process
>done.
>[root@hgt001 root]# service gm start
>Starting gm... active mapper... done.

And on the last lines of dmesg, I saw these.

>GM: WARNING: 
drivers/linux/gm/gm_arch.c:1368:gm_arch_lock_user_buffer_page():ker
>nel
>GM: trying to register a page with count 0

Sometimes I also see this message in dmesg too. 

>GM: Application closed file descriptor while mappings still alive: port 
destruct
> delayed

If I should attach some other message, please let me know. 
Thank you very much in advance.

(Additional odd thing)
BTW... while I did gm stop/gm start so many times, I suddenly see that the 
mapper 
process properly worked.

But I couldn't make mpirun work because of the message below.

>[root@hgt001 basic]# mpirun -np 4 ./cpi

I confirmed the memory is not full... 
After I rebooted the system, again I see the mapper process doesn't work 
anymore.

Do you have any idea why my environment is such unstable ?????

I guess you should provide the output of

/etc/init.d/gm start

and provide the output of the last lines of dmesg
