I also get a lot of these.
I have a fairly complex setup, lots of pools (~9,000) in a failover setup. I 
get a lot of the "peer holds all free leases" messages.
Server 2 doesn't seem to give any addresses out for certain pools.

Our setup is running 3.0.5 on Solaris. Would this just be "one of those 
things" - we can't simply down one box to purge the leases - this is a 
highly critical environment.

Any thoughts?
