Hi,

After a recent upgrade to p5-Net-Server-2.005 on various boxes, I'm 
finding that munin-node is going down regularly.

(Multiple machines, looks to be affected on FreeBSD8.2 and FreeBSD8.3 
REL, but not 9.0 machines)

It looks related to trying to start on an ipv6 interface ( which is not 
there) and i suspect this is a default from the perl Net-Server module 
rather than munin?
