I am replicating a database on the same installation.
8.0gb replicates to 7.4gb and 8.0gb_replica.
gb ---> gb_replica both on an 8.0b2 installation.
   |
   +--> gb on an 7.4 installation.

This set up may be somewhat strange, but it *should*
work. IMHO.  

When I start the three slon processes, the ones
against 8.0 report that there is already a listener
on the port. The logs are at the bottom of this message.

Also when I try to kill -TERM the slon processes one
set does not respond.  This may be the cause of my
problem?

Can someone point out a configuration mistake?  Or
is this a bug?

Starting up slon processes
--------------------------
slon gb "dbname=gb user=postgres port=5434 host=localhost" > slon_gb_74.out 2>&1 &
slon gb "dbname=gb user=postgres port=5430 host=localhost" > slon_gb_80.out 2>&1 &
slon gb "dbname=gb_replica user=postgres port=5430 host=localhost" > slon_gbREP_80.out 2>&1 &


This is my setup:
