Ethereum Error Reading from Database Shutdown: Troubleshooting Guide
The “Error reading from database, shutdown” error is a common issue that can occur when using Bitcoin Core 0.14.1 on Windows 10 Home v. 1703. In this article, we will help you troubleshoot and resolve this error.
Understanding the Error
Before diving into the solution, it is important to understand what the “Error reading from database” shutdown signal means. The Bitcoin Core daemon shuts down when:
- Encounters an inconsistent or corrupt database
- There are multiple Bitcoin Core instances running at the same time, all trying to access the same database
The error message indicates that the daemon has detected a database problem and is shutting down.
Troubleshooting Steps
To resolve the issue, follow these steps:
- Stop Bitcoin Core: Immediately stop all running Bitcoin Core instances using the command line:
bitcoincontrol --stop
This will ensure that there are no multiple instances running 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\[YourUsername]\AppData\Local\Masternode\databases). Completely delete this folder, including all subfolders and files.
- Check for corrupted files:
Manually search for corrupted or inconsistent files in the database folder. Check for files with incorrect permissions (e.g. `ownerdoes not match the group) or missing files altogether.
- Rebuild the database
:
If steps 1 and 2 resolve the issue, you can rebuild the database manually using the Bitcoin Core command line:
bitcoincontrol --rebuild
- Check for conflicting services:
Make sure there are no other services running on your system that may be interfering with access to the Bitcoin Core database. Some examples of conflicting services include:
- Windows Services: Some Windows services, such as the w3wp.exe
service (used by Internet Explorer), can cause conflicts with Bitcoin Core.
- Third-party programs: Any programs installed with Windows 10 can also interfere with access to the Bitcoin Core database.
- Update Bitcoin Core:
Make sure you are running the latest version of Bitcoin Core. You can check for updates using the following command line:
bitcoincontrol --update
- Disable additional services:
If you suspect that another service is causing conflicts, try disabling it temporarily and see if Bitcoin Core resolves the issue.
Preventing future issues
To prevent similar errors in the future:
- Regularly update your Bitcoin Core installation to ensure you have the latest security patches.
- Use a secure and isolated wallet (e.g. mywallet.pks`) for testing purposes or when running multiple copies of Bitcoin Core simultaneously.
- Always follow best practices for protecting sensitive data, including proper file permissions and access control.
By following these troubleshooting steps and considerations, you should be able to resolve the “error reading from database, shutdown” issue caused by Bitcoin Core 0.14.1 on Windows 10 Home v. 1703.
