bitcoin-qt crashing on startup (ubuntu) [RESOLVED: Faulty RAM]

OK, eventually I ended up removing the blocks and chainstate directories, and recovering from a backup I made in April. Re-syncing from there took a while, but it worked. Apparently, the issue was a rare kind of glitch on my system; I'll be making more frequent block chain back-ups in the future.

OK, not much help from the core dump here. Apparently, the failure happens in a background thread that originates from the levelDB code, not from the Bitcoin core code. So it could be related to any already-loaded LevelDB database.

Now, while I'll do some further debugging, does someone know where to find the database lay-out used in Bitcoin's LevelDB databases? I'd like to know how I can recognize inconsistent states, and recover Bitcoin to a consistent state.


EDIT:
Apparently, .bitcoin/blocks/index/LOG gets rewritten after each attempt to start bitcoin-qt. The most recent contents right now is:

Interestingly, there is a 053994.ldb in the directory. So, my current guess is the error is in that file.

EDIT 2: apparently, every time I re-start bitcoin-qt, it creates a couple of new .ldb files in that directory. I don't know yet whether that's a good or a bad thing though.

I'm having the same error right now, with Bitcoin-qt 0.9.3. After downloading and processing several weeks of new blocks, it crashed, and now it doesn't start anymore:

Code:
$ bitcoin-qt -wallet=empty.dat -debug

I don't think I have bad RAM, but  guess it doesn't hurt to do a RAM test. Anyway, the error now happens consistently a few seconds after start-up of bitcoin-qt, and I think it's unlikely it would hit the same RAM error each time in the same way. So, even if it was initially caused by a RAM error, right now it seems something is wrong with the state of the (block chain?) data on my disk, which is blocking me from re-starting bitcoin-qt.

Can I draw the conclusion, based on the log lines "Opened LevelDB successfully", that the error is NOT in .bitcoin/blocks/index and NOT in .bitcoin/chainstate? Based on the source file that reported the error, I'd say it has to be in something LevelDB-related. What does Bitcoin do AFTER successfully opening .bitcoin/chainstate?

I'll see if I can make a core dump and examine the function call stack. In the mean time, please reply if you know something that could help. My objective right now is to try to repair the files on my disk (e.g. removing the last ones that might be corrupt), in the hope that I can recover from this situation without re-processing the entire block chain again.

Hey, thanks for your ongoing help...

for some reason

Ran a RAM test overnight, I think I know what the problem is now   :-)   :-(

Kinda explains a few other minor oddball things I shoulda paid more heed to at the time.

Dont worry about the BETA label hehe all crypto-currencies are still in beta Wink


Looks like in the second run it started fine just fine and in the second it crashed while loading the blocks.

What do you have in your bitcoin.conf? I always recommend to install the bitcoin client from the sources but Im also using the bitcoind from debian repositories and didn't have any problems Sad

If you run bitcoind with -daemon (to run it in the background) or in one terminal and in another one doing a bitcoind getinfo do you get something?

In any case Im betting on the chance that the database of blocks has been corrupted for some reason, but lets check the rest first Smiley

Thanks for replying.

So I installed bitcoind (via sudo apt-get install bitcoind) and ran it as suggested:
Code:
jaymax@Antec:~$ bitcoind -debug

And a third run had three additional lines at the end - very odd.

Is there anywhere else I should be looking?

Hi!

Did you try running bitcoind alone? with the flag -debug to see everything that it does, just in case is not a problem with bitcoin-qt but with the actual client.

Hi.  It's a long time since I've used linux, but decided my newly engaged bitcoin adventure was a sensible time to see how things have moved on.  So far, no so much fun.  Appreciate any help I can get.

So, having established an offline LiveCD environment wallet for safekeeping, it was time to install ubuntu to the HDD and get a sync'ed up bitcoin-qt client running, and try sending over some coins to it...  Ignoring for a moment my puzzlement as to why I can install the client from CLI (sudo apt-get install bitcoin-qt) but not from the Software Centre, I've removed and reinstalled the client against the existing data files, with no effect on the error.

The b-qt was syncing up okay, got to about 300 days to go when I last checked, but then died at some point.  This is what seems to be appended to the debug.log (db.log is zero bytes) with each attempted restart:
