Hi there, I am trying to increase the amount of shared memory on my Mac OS 10.4 machine (i have 5 GB RAM installed), but without too much success. My /etc/sysctl.conf file looks like this: kern.sysv.shmmax=33554432 kern.sysv.shmmin=1 kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.sysv.shmall=8192 Then I reboot and do sysctl -a | grep shm, and read: kern.sysv.shmmax=4194304 kern.sysv.shmmin=1 kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.sysv.shmall=8192 4194304 is the default value for kern.sysv.shmmax. It looks as if Tiger ignores my feeble attempt to set the kern.sysv.shmmax value. Any pointers? BTW, as I intend to allow 240 connections I should probably raise the settings even way beyond that, I am just still experimenting.
