zend should connect to our SeedNodes at startup to find the initial nodes. Can you make sure you can ping the domain names here please?

dnsseed.zensystem.io
dnsseed.zenseed.network
zpool.blockoperations.com
node1.zenchain.info
mainnet.zenseed.network
mainnet.zensystem.io

This is a normal message that often persists after an initial syncing, usually a restart of zend "fixes" it. In fact the message is just erroneous, the blockchain is usually still being added to (as can be seen by increasing blockcount). @tarrenj I haven't looked into it, but there is something in the code that spits this warning out but seems to be based on flawed or non-updating logic. Probably worth chasing down the exception tree.
