Re: SHMMAX seems entirely broken in OS X 10.4.2 - Mailing list pgsql-hackers

This is from my Powerbook

in /etc/rc

sysctl -w kern.sysv.shmmax=5120000 kern.sysv.shmmin=1  
kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.sysv.shmall=1024

I also had to up maxprocperuid to 200 to get buildfarm to run

I'm pretty sure shmall had to be increased to allow shmmax to be  
increased.
