bitcoin core v.26 shuts down without warning - Doesnt save blocks downloaded

Rucade commented at 11:21 am on January 30, 2024: none

Is there an existing issue for this?

I have searched the existing issues

Current behaviour

bitcoin core v.26 shuts down all the time unexpectedly, crashes and asks to Force Quit or wait so it does not save the blocks downloaded unless I shut it down first which is a terrible task every few minutes. I am at June 22nd 2023 for days trying to download the rest of the blocks. How do I fix this “bug”?

Expected behaviour

to get the core loading properly I need to fix this bug or ERROR REPLY from Canonical: Please open a bug using this link: https://help.ubuntu.com/stable/ubuntu-help/report-ubuntu-bug.html.en

Steps to reproduce

Emailed Canonical and Qt.io

Relevant log output

I cant open the debug log

Please check your debug.log for possible causes; Alternatively you can upload it here.

You can find the debug.log in your data dir.

Please be aware that the debug log might contain personally identifying information.

Bitcoin Core makes heavy use of CPU, RAM and disk IO. Hardware defects might only become visible when running Bitcoin Core. You might want to check your hardware for defects.

memtest86 to check your RAM
to check the CPU behaviour under load, use linpack or Prime95
to test your storage device use smartctl or CrystalDiskInfo

2024-01-19T10:49:39Z Bitcoin Core version v22.0.0 (release build)

Are you sure you are running 26.0? Your logs claim 22.0.

You may be right there. I had v.22 but I downloaded v.26 later because of serious errors and it may have kept the debug log from 22 but I did erase all the blockdir and started again fresh. So, should I erase everything delete all the files in .bitcoin linux ubuntu and start fresh on windows?

This sounds most likely like a hardware malfunction to me too.

In any case you could try rotating your debug log (to start a fresh one) and this time be sure to use v26.0, then upload that debug log here if the problem persists? Something like:

0# rotate debug log
1$ mv ~/.bitcoin/debug.log ~/.bitcoin/debug.log.1
2
3# check that you are going to run v26.0
4$ bitcoind --version
5Bitcoin Core version v26.0
6Copyright (C) 2009-2023 The Bitcoin Core developers
7
8# Start v26.0
9$ bitcoind

This might not tell us much more if the issue is hardware-related, with a few checks you can do to try and determine that detailed above by maflcko.

Can you provide any additional hardware details?

Careful running the following sudo commands below if you are not sure what they do

CPU: model (can check with lscpu | grep "Model name"
HDD: type e.g. SSD, spinning disk (check with sudo lshw -class disk -class storage or smartctl as described above)
RAM: size (GB), type (e.g. DDR4) (check with sudo dmidecode --type memory)

So, should I erase everything delete all the files in .bitcoin linux ubuntu and start fresh on windows?

If it’s a hardware issue and you have both OSes on the same machine, I wouldn’t expect this to help much. If these OSes are different machines, then I would expect this to help.

Hey @Rucade, I’m going to close this now as I don’t think there’s anything to be done on the Bitcoin Core side.

Feel free to open a new issue if this re-occurs fo you using v26.0
