Blockchain gets stuck downloading no matter what

[hatrix]

I don't know what to do, I've tried everything I could find on the forum.

I installed bitcoin-qt fresh on my windows install. Started it and let it run for an entire day but when I looked at it later that night noticed it was stuck at like 93% of the blockchain downloaded. Tried to quit out and use the -rescan option. That didn't work, the error message at the bottom displayed was: "Warning: displayed transactions may not be correct! you may need to upgrade, or other nodes may need to upgrade"

I tried searching for that error too and nothing that was said resolved the issue. I have tried deleting all my blk files in the data directory and letting it redownload the entire blockchain again and it gets stuck downloading every single time. The last time I tried letting it run the error message from before popped up without me ever even restarting the client, the one about displayed transactions may not be correct.

Tried uninstalling and reinstalling bitcoin-qt. Did not work.

Made sure I had enough diskspace, there's plenty of free space for the blockchain.

I have tried using snapshots of the blockchain with a new wallet and it STILL got stuck downloading with the same error as usual popping up after a while.

I don't know what is wrong. It's driving me crazy. I can't access anything stored in my actual wallet because the blockchain won't finish downloading. I was going to say screw it and use my online wallet but I need to import my private keys for that wallet, but can't because bitcoin throws the same error I get about not being up to date when trying to dump.

I have 8 active connections to the network according to the client yet nothing more will download.

This is the error being dumped in the log repeatedly:

I have 8 active connections to the network according to the client yet nothing more will download.

if you're using the default directory, delete all the stuff in your /users/<name>/appdata/roaming/bitcoin folder. 

make a new bitcoin.conf file

server=1
daemon=1
rpcuser=crazedhookers
rpcpassword=3$9czKO$23LCXMZJO%$#@vndkxccxkvDJSKOJ%#@OPvfcxkvjW$JRO#$@
rpcallowip=127.0.0.1
rpcport=31337
port=8333
listen=0
maxconnections=1
irc=0
upnp=0
keypool=0
dns=0
detachdb=1
logtimestamps=1

connect=5.9.24.81

after blockchain is done downloading, change maxconnections, change listen to 1 (if you want), and remove connect=5.9.24.81, or change it to addnode or something... and I guess you could change keypool to make a ton of addresses you probably wont need to bloat your wallet some

[hatrix]

why do I need that specific username and password for the config file ?

And yea like I said, I've deleted the data folder multiple times and retried.

I'll report back in the morning, I know it's going to take forever as usual to download.

[Stephen Gornick]

I don't know what is wrong. It's driving me crazy.

Are you using the latest release of the client, v0.7.2?

[ingrownpocket]

Import your wallet here:
https://blockchain.info/wallet/import-wallet

[hatrix]

Still failed to finish downloading. Stopped aroud 82% and this time I had zero connections to the network when I checked.

Yes I'm using the latest client. I'll try the online wallet, didn't know you could use your wallet.dat

Screw it, I'm done with the client. It's giving me to much trouble and I don't know why. I never noticed that import page on the online wallet, if you were logged in it only let you import with other methods for some reason.

I had the EXACT same problem

Both of these are correct block hashes for the main chain; it looks like one p2p client you are connecting to might be serving you up a corrupted block 139548, confounded with some problem recovering to a correct blockchain. We would need to look further back in the log file where blocks up to 139548 are downloaded normally and then something happens to see when the problems started occurring and deduce what data Bitcoin might be receiving. If you can post the complete debug.log/db.log files from download start to blocks 140000+ on the web somewhere it might help.

If you want to skip quite a bit of downloading, you can get this torrent: https://bitcointalk.org/index.php?topic=94881.0 - -loadblock it's orphan-free blocks instead, which definitely shouldn't error.

Scroll bar. Use it.

Bitcoin also requires a computer that is operating correctly, it runs the CPU and drives at 100% for hours, and has low tolerance for bad math. It requires about 100 trillion CPU instructions to download the blockchain, all performed correctly. If you have a laptop that has the cooling fins plugged up with fuzz, are overclocking, have a SATA cable creating CRC errors, or have one bit of bad RAM, Bitcoin will find it.

I'm experiencing exactly the same problem, by using the official Debian package:

http://packages.debian.org/sid/bitcoin-qt

So, is this a bug?

Actually I deleted the broken blockchain, and currently I'm re-downloading everything.

Ciao!

[Herodes]

it should also be possible to get the blockchain off torrent to get up to speed. Sadly I don't have a link, perhaps some others do ?

Finished. No problem this time.

Great! Is it the first time with bitcoin ?

HA! Nice! First time I notice this.

lol, must've been when it was at 1337 posts.

[jomplox]

Give Electrum a try. It has all the same features and doesn't need to download the blockchain.

[Stemby]

No, but it is the first time with the official package taken from Debian repositories.
