I'm having an issue downloading the bitcoin blockchain on a new computer. I downloaded it all day yesterday without issue (80% downloaded) and then when I woke up this morning the computer was still on but Bitcoin Core was closed. I looked at the error log and didn't see any reason as to why it closed.

Here's the debug log from first thing in the morning prior; no errors or anything that stands out to me, it just abruptly ends:

I opened Bitcoin QT and just tried to have it keep grabbing blocks to see if it would finish downloading or if it would run into an error. I left and once again came back to a computer that was still on, but Bitcoin Core was closed.

Here's the debug log from this second closure; similarly no clear errors and just an abrupt ending

I tried again to just run Bitcoin QT to see if it could finish grabbing the blocks or if an error would at least populate. It did shortly after populate some errors saying something among the lines of "couldn't access block #### data" (in hindsight I should've screenshotted the error popup).

Here's the debug log from this third closure when an error populated. This one similarly ended abruptly at the bottom of the debug file, but it at least had some errors earlier in the debug file (the only time that the word error was referenced in any of these files). After the Error, it seems to resume as normal, and then just cut off abruptly

Then everything in the debug file looked normal for a while, no additional errors, and similar to the first two examples, the file just ends abruptly.

  • It is far better to cut and paste logfile records than to post an image. We can't use text search etc in images. Sep 10 at 13:25
  • @RedGrittyBrick Certainly appreciate the feedback as I'm new to this. Would the best practice be to just truly paste all the text in the post, or should the text be input in a specific way? I'm unfortunately away from the PC where I'm trying to install the node until Monday/Tuesday so depending on best practice maybe I should delete this and try reposting in a few days. Thanks again!

  • I would just edit the text in whenever you are able. This could be a big help to future people with the same problem who are using Google etc to search for help on some text in a logfile. Don't worry about the amount of text (within reason), so long as you mark it up as preformatted text (use the {} widget above edit-area or press ctrl+k) -- it will not take up too much space on the page - it will get scrollbars for each textarea.

  • Amazing, thank you sir! Sep 10 at 15:02

I don't see anything obvious in the log but there's a few items of interest

At 17:57:59 it says Config file: D:\Bitcoin\bitcoin.conf (not found, skipping) which suggests you have specified a non-standard data directory, perhaps by a command-line option? The apparent absence of bitcoin.conf may be unusual - my installation has an empty file with that name.

Command line options when running Bitcoin-qt:

-conf=
Specify path to read-only configuration file. Relative paths will be prefixed by datadir location. (default: bitcoin.conf)

-datadir= Specify data directory

Then at 17:58:27 there is Failed to open mempool file from disk. Continuing anyway. I've no idea if this is significant. It suggests an abnormal shutdown if you didn't previously set the option to not persist the mempool.

At 17:58:27 there is Failed to open file D:\Bitcoin\anchors.dat which confirms that bitcoin-qt didn't exit normally previously. It creates this file when it exits.

This doesn't give much direction for tracking down the problem.

You could create an empty bitcoin.conf and verify that the warning about that file goes away. You could perform a memory test to ensure that bitcoin-qt isn't using a lot of memory and therefore being affected by some problem not evident in less demanding applications - but this seems like a long shot. You could invoke bitcoin-qt.exe from a .bat file and put echo Exit Code is %errorlevel% after the invocation. Give that you had a pop-up error dialog stating"couldn't access block #### data" - you might have corrupt blockchain data files. There are open-source parsers that can read these blockchain files and that might help verify that one has a problem. You might need to uninstall, clean up, reinstall and restart.

    Thank you for taking the time to look at this. I imagine the the improper shutdown was the computer resetting at some point. The path is not standard as I have the blockchain loaded on a external Samsung SSD so it's not on the bootdrive (this shouldn't cause issues normally should it?). I'm still not totally sure what went wrong previously, but I ran the reindex feature and came back this morning with the client totally synced and finished, so that seemed to fix it somehow.

  • So a few times now I've come back to this computer after leaving it alone for a few days and I come back to "error reading from database, shutting down". This has happened twice now in the last couple days and then I just re-run bitcoin-qt and it typically resyncs the missing blocks in just a few minutes and gets back up-to-date. Any idea what would be driving this? The computer is brand new. Sep 29 at 18:39
