Here is the error I'm getting:

I have re-compiled my kernel and increased SHMMAX.  Are there some other memory settings I should be making?

I am running Red Hat 7.0 with all patches.

All help appreciated.

Chris.

Are you sure you have 273 MB of memory and want to dedicate all to shared
buffers?  I don't believe that will help a lot.
