Hi to all.
I have some doubts about how slony-I replication process works.
I Have one master and 4 slaves that share some tables.
I create a cluster script and run it. After i run slon daemon in all nodes. 
At 
the end i run subscribe script. After this operation my server (linux) show 
messages but i don't undestand if this is normal or what are. After 2 hours 
it 
still show me message like these:

and so on.
What happen? I need to restart some process or wait the end of the process?

Please help me.

Thanks to all
