You could, but I would try just doubling whatever it is to see if  
thats improves the issue first.  The default is 32MB.  You could  
double it to 64MB and test again.

What is it currently set to (run: sysctl kernel.shmmax)?  You can  
change it on the fly with sysctl.  Once you're done testing and want  
it to persist across reboots, you'll want to set in /etc/sysctl.conf .

Cheers,
Rob
