Connection's limit in SCO OpenServer 5.0.7 and pg 8.3.11 (no more than 94 connections)

Hello! I have postgres running on SCO OpenServer 5.0.7

and I've noticed that only accepts up to 94 connections, no more ...
I modified the values in postgresql.conf
max_connections from  100 to 128
shared_buffers  from 24 to 48  MB

postgres is started  with:
su - postgres -c "/usr/local/pgsql83/bin/postmaster -i -D
/usr/local/pgsql83/data"




I rebuilt the SCO kernel with these values:


NODE    "srvr83"
EVDEVS    96
EVQUEUES    88
NSPTTYS    64
NUMSP    256
