or you can let sysctl do it with this in /etc/sysctl.conf:

kernel.shmmax = 268435456

(obviously changing the value with what is appropriate for your machine).

This is for a RH 6.2 box.  DOnt know if its the same on 7.1.  We switched to
FreeBSD between redhat 6.2 and 7.0, so we dont have any RH7.1 boxes laying
around.  I suspect it hasn't changed though.
