Hi all,

I'm running a master with two slaves, and one of the slaves forwards  
to an offsite node (so, 4 nodes in all).  Each node is replicating 3  
databases

Since finishing the setup, I've been experiencing high load on all 4  
nodes, and I'm not sure what's causing the problem.  A quick glance  
at 'top' shows that the top cpu-consuming processes are postgres  
processes run by the slon daemon.  A handful of them say "notify  
interrupt waiting"

Any ideas why the load is so high (anywhere from 4.00 to 6.00)?   
Before doing this setup, I've experienced loads around 0.80 to 1.70

Any insight would be greatly appreciated!
