Normally everything is working pretty fine, but sometimes it seems that other nodes produce an enormous amount of traffic. I have not had the time to investigate thoroughly yet. I only have briefly viewed with tshark. So far I have just restarted the client in the hope that it no longer connects with the 'evil' node. This usually works quite well. Is anything about DOS-Attacks known to you? Many new users have started using the reference client which downloads the whole blockchain from peers.

Yes I have made a clean start because of the the new database structure. There currently isn't a throttling mechanism [1] so it's possible to quickly eat up your bandwidth.

I successfully have downloaded the Blockchain again. Thus, it should not occur again now. If it does, I'll be back again. :-) Thank you for your quick help. regards Oliver -- Minimize network downtime and maximize team effectiveness.

BTW, check out the blockchain torrent, as one way of offloading some of the download bandwidth used from the P2P network: Bitcoin blockchain data torrent https://bitcointalk.org/index.php?topic=145386.0 -- Jeff Garzik exMULTI, Inc. jgar...@exmulti.com -- Minimize network downtime and maximize team effectiveness.
