Testnet was recently reset; try upgrading your client.

I'm running on testnet, and chain download gets stuck at ~53546 blocks remaining ...
Anyone knows why ?
Which is the last block you have? It seems my client is stuck, too and has 6897 blocks. Edit: I'm seeing a few of these 06/04/12 09:19:20 ERROR: CheckProofOfWork() : nBits below minimum work 06/04/12 09:19:20 ERROR: CheckBlock() : proof of work failed 06/04/12 09:19:20 ERROR: ProcessBlock() : CheckBlock FAILED Dia

I just got stuck-- looks like somebody is serving up the testnet2 blockchain to testnet3 nodes that connect to them (that's what is causing the 'nBits below minimum work' message).
Re-running to connect to a real testnet3 node is getting me the correct blockchain (with 6,905 blocks).

Gavin, is there any way, to send the old nodes on testnet an alert message to upgrade?

It quickly downloads the blockchain (about 6K blocks), then claims to be up to date, and then, 30 seconds later claims to be 50K+ blocks behind.
Bitcoin-Qt ? Sounds like a bug in the "estimate how many blocks there are based on what your peers tell you" bug.

That may very well be, but I'm generally surprised to see that a testnet "reset" has so many dependencies left on the old chain.
Would it be possible to have bitcoin-qt refuse all testnet packets from a peer that identifies as being below a certain version ?
Yes... but having peers with a completely different block chain from you connect is a good way to shake out obscure bugs. Like Bitcoin-Qt's "how many blocks are in the valid chain" code getting fooled...

I also have the same problem =( I compiled latest bitcoin-qt from github to test the new translations.

I'm not sure where this bug is coming from, as the GUI client does: int ClientModel::getNumBlocks() const { return nBestHeight; } and int ClientModel::getNumBlocksOfPeers() const { return GetNumBlocksOfPeers(); } Edit: I checked the debug.log and not a single node was reporting a version in the version message, that indicates, it even knows about a testchain reset.

hmm... I downloaded the latest sources from git and now testnet3 works again... BTW I get testnet2 working as well with Bitcoin Wallet for android.
Was there a bug that collided these two networks?
