Hi all,

I just installed pg 8.0 on freeBSD 5.3.

All  is ok, but if I try to increase max_connections to 256 (or more) pg
do not starts.

Yes, I readet the docs and I know that I need to increase shared memory
and semaphores.

I recompile my kernel and set :
options         SYSVSHM
options         SHMMAXPGS=16382
options         SHMSEG=9182

options         SYSVSEM
options         SEMMNI=9182
options         SEMMNS=9182
options         SEMMNU=9182
options         SEMMAP=9182


And also after installing the new kernel I got the same error.

Pls., help me to find the values of  semaphors in my kernel.
Exist any tools for this info?

many thanks,
ivan.

The following works for me on 5.3

options         SHMMAXPGS=131072
options         SEMMNI=128
options         SEMMNS=512
options         SEMUME=100
options         SEMMNU=256
