bad_alloc means the process failed to allocate new memory. Most likely the code is trying to allocate a ridiculous amount of RAM (possibly some badly derserialized varInt).

Download the testnet chain and try to build that. Also, could you give me your first block file? (blk00000.dat)

The bootstrap does not cover all of the blockchain. It is usually updated along with Core updates, as milestone hashes are hardcoded in. Downloading the bootstrap will only give you history up to a certain point in the past, the rest has to be downloaded straight by Core itself, and Armory can only display your up to date balance once you have an up to date copy of the blockchain locally.

Start BitcoinQt, let it finish downloading blocks. Once it is fully sync'ed, start Armory. It should be able to figure it out on its own. If it fails, do a rebuild and rescan.
503  Bitcoin / Armory / Re: Armory - Discussion Thread on: August 16, 2015, 11:31:12 PM
Possibly some bad blocks. Try to sync the testnet chain, see if you get the same symptoms.
504  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 16, 2015, 09:35:46 PM
This looks severe. Do a Help -> Rescan and see if it you get the same output.

Although I am running on 0.93.2 I can report as much. My desktop has been running Armory for more than a year now and I've had no issues or crashes at all. Zero. My laptop however, is a different issue. Whenever I wake it up from days of inactivity, Armory quickly throws a "missing headers" error and quits, only to return with full functionality on next launch. At first I didn't know if it was an issue with sleep or just it not being able to keep up with bitcoind but today for the first time it happened on the desktop.

We had a power failure yesterday and after restoration there was no internet until just about now. During all this time Armory had been running uninterrupted. When the internet came back, bitcoind began catching up with a day's worth of blocks, and Armory threw the "missing headers" error.

Could you please investigate if there are issues with Armory keeping up with bitcoind when it's behind by say 2-3 days and suddenly it gets a chance to catch up?

I am re-reporting this in the ongoing bigger Armory thread to keep a 0.93 error off the 0.94 post but since you are investigating this now, I figured I'd mention it here as well.

That's a 0.93 specific issue that has been fixed in 0.94

0.93 can't tell the difference between a mangled block and a block in the process of being written to disk (which appears mangled when Armory reads it). 0.94 side steps the issue by rereading partial blocks at each iteration until the partials either fill up or a valid block further in the file extends the chain.

The true solution would be to listen on the new block P2P notification and grab data over the socket, but that's a whole new effort.

Armory constructs merkle roots, computes block hashes and figures out the longest chain. It will also detect double spends on ZC transaction. Armory does not have an implementation of consensus rules, and thus cannot verify that transactions nor blocks respect them.
507  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 14, 2015, 11:17:33 PM
I fixed this issue in the last commit a couple days ago. Pull again and give it a spin.
508  Bitcoin / Armory / Re: Armory Not syncing up to current height on: August 10, 2015, 10:15:21 AM
You can delete blk and rev files past the stuck point. It will only download the missing blocks but you'll have to reverify the chain in full.
509  Bitcoin / Armory / Re: transaction didn't broadcast and I can't find mempool.bin for v0.93.2 on Ubuntu on: August 10, 2015, 10:13:49 AM
I assume you mean Armory's mempool? There is no more mempool.bin in 0.93.2. Zero conf transactions are saved in the DB now. You can wipe that container using Help -> Clear All Unconfirmed
510  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 10, 2015, 10:11:12 AM
On the first run I got another error about missing headers, a suggestion to do a factory reset, and a forced close. I choose to not do a factory reset

This error marker is very aggressive, you shouldn't do a factory reset unless you run into it a few times in a row. I should do something about it really, at least not let it trigger on missing headers only.

Try the latest commit with your damaged DB.
512  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 09, 2015, 01:26:07 PM
Thanks, that will help a lot.

Please find the ZIP password PM-ed. I've encrypted the ZIP just in case it has some privacy implications.

It does, encrypting it is proper practice.

You can also all see them in source with the attached description string:

514  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 09, 2015, 11:40:26 AM
This happens every time I run Armory. I could probably reset this to working by removing ~/.armory/databases and starting over.

Yes, you will have to rebuild & rescan or delete the DB folder

Perhaps my "databases" would be useful for you? I can put it online if you need.

I would like that very much. If I can experience the issue first hand I can improve the DB repair code to catch that one too.
515  Bitcoin / Armory / Re: Starting preliminary 0.94 testing - "Headless fullnode" on: August 08, 2015, 08:30:57 PM
Does it fix itself after a restart?

https://github.com/etotheipi/BitcoinArmory/blob/master/cppForSwig/EncryptionUtils.cpp#L75

This is how root keys are created,

https://github.com/etotheipi/BitcoinArmory/blob/master/armoryengine/PyBtcAddress.py#L765

This is how the rest is derived.
517  Bitcoin / Armory / Re: armory downloaded block chain twice on: August 08, 2015, 12:09:22 PM
This is how Armory's DB has always worked. It copies all block data over to its own DB. If you want to light version, build 0.94 from source and try it out, it's in the ffreeze branch.
518  Bitcoin / Armory / Re: Resource hogger and how to move large BLOCKS files? on: August 08, 2015, 12:07:53 PM
Use the --dbdir command line argument to target a custom db path. You can move the current files there, no need to rebuild from scratch. There's no option in the GUI for that purpose, what you are using is to tell Armory where to download and look for the raw block chain data when auto managing Core.

What's your disk bandwidth at?

are you displaying change addresses in the wallet's property window?
