Ethereum Error Reading After Database Shutdown: Troubleshooting Guide
The “Error reading from database, stopping” error is a common problem that can occur when installing Bitcoin Core 0.14.1 on Windows 10 Home v. 1703 systems. In this article, we will help you troubleshoot and fix the problem.
Error Interpretation
Before we dive into the solution, it is important to understand what the “Error reading from database” stop signal means. The Bitcoin Core daemon stops when:
- Finds an inconsistent or corrupted database
- Multiple instances of Bitcoin Core are running simultaneously and trying to access the same database
The error message indicates that the daemon has encountered an error in the database and is stopping.
Troubleshooting Steps
To resolve this issue, follow these steps:
- Stop Bitcoin Core: Immediately stop all running instances of Bitcoin Core from the command line:
Bitcoincontrol --stop
This will ensure that multiple instances cannot run at the same time trying to access the database.
- Delete the database folder:
Locate the “db” folder in your Bitcoin Core data directory (usually located at “C:\Users\[username]\AppData\Local\Masternode\databases”). Delete this folder completely, including subfolders and files.
- Check for corrupted files
:
Manually check the database folder for corrupted or mismatched files. Look for files with incorrect permissions (e.g. “owner” does not match the group) or files that are completely missing.
- Rebuild database:
If steps 1 and 2 resolve the issue, you can manually rebuild the database using the Bitcoin Core command line:
Bitcoincontrol --rebuild
- Check for conflicting services:
Make sure you don’t have any other services running on your system that could interfere with Bitcoin Core’s database access. Some examples of conflicting services:
- Windows services: Some Windows services, such as the w3wp.exe service (used by Internet Explorer), can cause conflicts with Bitcoin Core.
- Third-party programs: Programs installed alongside Windows 10 can also interfere with Bitcoin Core’s database access.
- Bitcoin Core update:
Make sure you are using the latest version of Bitcoin Core. You can check for updates using the following command line:
Bitcoincontrol – update
- Disable additional services:
If you suspect another service is causing conflicts, try disabling it temporarily and see if Bitcoin Core resolves the issue.
Prevent future issues
To prevent similar errors from occurring in the future:
- Update your Bitcoin Core installation regularly to ensure you have the latest security patches.
- Use a secure and isolated wallet (e.g. “mywallet.pks”) for testing purposes or to run multiple instances of Bitcoin Core at the same time.
- Always follow best practices for protecting sensitive data, including appropriate file permissions and access controls.
By following these steps and troubleshooting tips, you should be able to fix the “Error from database, stopped” issue caused by Bitcoin Core 0.14.1 on Windows 10 Home v. 1703 system.
