I'm on the Satoshi QT client, version 0.6.0.6-beta.

At some point on 23 April 2012, the client crashed in boost library code (unfortunately I didn't save the error message) and since then the client has been unable to make progress in catching up to the network; it's stuck at block 176947. I tried -rescan with no success.

Does anyone know what might be causing this?

If there is something that will make Bitcoin succeed, it is growth of utility - greater quantity and variety of goods and services offered for BTC. If there is something that will make Bitcoin fail, it is the prevalence of users convinced that BTC is a magic box that will turn them into millionaires, and of the con-artists who have followed them here to devour them.
Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

About five hours.

Here's a pastebin.

I solved this by deleting the blockchain and copying it from a working client.

However, since this makes at least two people who have gotten stuck on this exact block, I suspect there's a deeper issue here that you guys might want to investigate independently.

At least three.

I noticed that my old client (0.3.x) was stuck at 176947 too when I was waiting for an incoming transaction. A backup only updated to the same block too.
Bitcoin had been closed normally before, no crash or anything.
Downloading the nightly blockchain snapshot and running bitcoin with the rescan option fixed the problem and the client just finished updating the last few missing blocks.
Seems like that block somehow differs from all the others.

Will the next person who gets stuck please get in touch with me via PM.  Peter thinks he fixed a dangling get stuck bug (https://github.com/bitcoin/bitcoin/pull/1196), but unfortunately its hard to reproduce the problem.   If you could cleanly shut down and make a copy of your bitcoin director then we could give you a fixed binary to test.

I'm stuck again. This time the block number is 181808.

Could I get a binary, or the command to pull+build a version of bitcoind with the fix?

I went ahead and applied the patch manually. It does NOT allow me to proceed past this block.

I'm going to go ahead and delete my copy of the blockchain now, in the hopes that I'll be able to make progress after the purge.

No good - I've gotten stuck at the same block again.

I would really appreciate some help here[/b]. It's getting to the point where it's not worth it to store my coins on this client anymore.

Are you mining? If not, perhaps you should consider switching to another, blockchain-less client?
I would suggest checking out Electrum and MultiBit, both are quite good and stable.  To compare their features, you can use my chart, which is up to date: http://dre.tx0.org/compare.htm (There's Armory too, but it's still in alpha for now)

Did you PM gmaxwell about this?
You could download the nightly snapshot and use this one to skip the block.

Yes.
Did you PM gmaxwell about this?
Yes, and I received no response.

Does the nightly snapshot have a fix other than the one mentioned in gmaxwell's post? Because I tried that fix and it didn't help.

Edit: Wait, do you mean a nightly blockchain snapshot? That could work.

Edit 2: It did, in fact, work. Hopefully it won't get stuck again...
