Has anyoone had similar problems ?

I have problems satting SHMALL on some linux (RedHat 6.2) computers

when I try to set them to 128MB (on a 256MB computer),
it has no effect.

[root@amphora2 /root]# echo 134217728 >/proc/sys/kernel/shmmax
[root@amphora2 /root]# echo 134217728 >/proc/sys/kernel/shmall
[root@amphora2 /root]# cat /proc/sys/kernel/shmall
4194304
[root@amphora2 /root]# cat /proc/sys/kernel/shmmax 
134217728
