Did that. On first run it took a long time and Armory produced a 92GB log file before I shut it down containing these messages:

Then I deleted blocks back to blk00600.dat, did a "bitcoind -reindex" and started Armory again after blockchain was up to date.
This time, everything worked as expected. Had to close Armory again because it comsumed again all memory while showing no progress for hours, but now I can start it without a problem.

New problem with the backup computer where I downloaded a fresh blockchain with BC 0.13.2. Now Armory hangs on "Initializing bitcoin engine" and ArmoryDB never gets started. armorylog.txt fills up with megabyted of this repeated error  message:


2017-04-23 16:27 (ERROR) -- SDM.py:791 - ValueError in bkgd req top blk

I also installed Ubuntu 16.04 on that computer to check if it is a problem with the operating system. Same problem.
Any advice?

Thank you for answering!

Meanwhile, before your post I startet to download a new blockchain with BC 0.13.1 on the backup computer, so waiting for this to finish before trying again.

On the main computer which halfway worked before, I downgraded to BC 0.13.2 and started Armory up with deleted database folder. This time, I had to kill ArmoryDB because it was getting stuck at "Scanning transaction history". In detail, I closed Armory when nothing happened for some time, then CPU usage suddenly jumped up with ArmoryDB for some time, but it didn't terminate, so I killed it. After a restart, everything seems to work and total sum shows up fine.

Posting log files from the main computer:

I have problems upgrading from 0.93.3 to 0.95.1 on Ubuntu 14.04.

What I do is:
- delete "databases" and "bittorrentcache" folders in .armory
- remove 0.93.3, install and start 0.95.1
- wait for the database being build (seems to work fine)
- see armory hanging at "Scanning transaction history" (showing no progress for hours)
- ArmoryDB will consume all available memory at this point
- close Armory, kill ArmoryDB process
- restart Armory
- it will finish to main screen, but this years transactions are missing, showing a wrong total sum of funds

This is on my backup computer. On my main computer, also with Ubuntu 14.04 and same wallets, ArmoryDB will also hang at "Scanning transaction history" but not consume all available memory. Also there are error messages when Armory is started from console. I can close Armory there with it shutting down ArmoryDB automatically. When I restart Armory, it completes and shows correct total funds.

dbLog.txt

In dbLog.txt there are errors "invalid header size" and "raw data does not match expected block hash". Should I redownload BC blockchain and try again with database rebuild?

Both main and backup computer have 16GB of RAM. Scanning from scratch taking some time is normal, but it just feels odd to me that ArmoryDB will consume 14GB on one computer and hang while it never consumes more than 4GB or less (I think) on the main one.  And a bit unsettling to see it finish with wrong total sum when ArmoryDB is being killed. I've been trying this for some days now btw, having waited for more than a day for the task to complete and also saw other non-reproducable erratic behaviour.

Anyways, should've done some more research than just searching forum and reading through this thread, apologies! Looking at dbLog.txt there seems to be a problem with some blocks. You can not use bitcoind >0.13.1 with 0.95.1 right? Will make an own thread if I'm still curious, Thank You!

I could just copy over everything from the main computer to backup computer, but havent't done so as I wanted to report the issue first.

Well, Flanagan's steps to verify differ in what's being said on the website as he uses pgp key 8C5211764922589A instead of  98832223. I guess both belong to goatpig?

Trying your antminer S1 cgminer build, I got:

/usr/bin/cgminer: can't load library 'libpolarssl.so.7

when starting cgminer.

Hello, I have a question regarding hidden workers. If one of my workers connects to the pool but is hidden, will its shares count on my balance? I ask because I have one worker which only connects to BTCGuild as failover pool, and I set it hidden because I have Idle Workers notifications enabled.

Also, cex.io mines on ghash.io which I wouldn't choose because of the 51% issue (it is already too loarge). We want to behave in a way to keep a sustainable ecosystem for us all. This is one of the lessons we learn with cryptocurrencies and I hope that people interested in cryptocurrencies are smart enough to behave in a way which benefits not only themselves but our ecosystem too. Should be doable because cryptocurrencies require a certain amount of education, but anyway let's see....
