Right now I'm trying to figure out why postgresql wants more semaphores
even though I've maxed them out with /etc/conf/cf.d/configure.

Bill,

I've found that if an application needs you to increase the number
of semaphores, you need to also increase the semaphore undo structures:

SEMMNU: number of semaphore undo structures.
The current value is: 150 (normally: 30)

I had already set this to 100, the max before configure starts
complaining.

When I tried setting this to 150, /etc/conf/cf.d/configure
bitches about it having a max value of 100 if I use the short
method ``./configure SEMMNU=150'', but I can override it in the
interactive mode (OSR 5.0.6a).

My rule of thumb is to set the system so that you run out of semaphores
before you run out of semaphore undo structures.

I have tried a multitude of options. My current stune is attached.

Bill
