Max Kernel.SHMMAX in SUSE10(32Bit) ?

Hi All B) ,

I am working on SUSE10(32 bit). I am trying to increase my kernel.shmmax. Max i am able to set is only 4GB. Even I set more than 4GB the system doesnt accept it !!! Is the maximum SHMMAX we can set is 4GB ? or Do we have any other way to set ?

I tried the follwing steps.

vi /etc/sysctl.conf

kernel.shmmax=8589934591( Edited to 8 GB )

/sbin/sysctl -p ( to reflect the changes in SHMMAX)

cat /proc/sys/kernel/shmmax

4294967295 ( still it shows 4GB ) :(

can any one support me on this ?

Thanks in Advance
