This is usually a symptom of a lease database inconsistency.  A
short-term fix will be to 'fault' the database on one of the servers
so the peer picks up a fresh copy and they have a consistent image to
start with.  It may slowly drift, I can't remember what we fixed after
3.0.5.

3.0.5 also predates POOLREQ storm bugfixes if I remember right,
wherein servers would never stop trying to perform lease database
balance operations...the first POOLREQs the second, which causes it
to POOLREQ the first, which causes it to POOLREQ the second...

This is probably why you get storms of these log messages.
