SQL Server Error Msg 3930 – The current transaction cannot be committed and cannot support operations that write to the log file

In this blog post, let’s learn about the error message “3930 – The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.” in Microsoft SQL Server, the reason why it appears and the solution to fix it.

SQL Server Error Message

3930 – The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.

Reason for the Error

The SQL Server Error Msg 3930 is raised when a transaction tries to perform an operation that requires writing to the log file but is unable to do so. The error message indicates that the transaction cannot be committed and should be rolled back.

This error can occur due to several reasons, including:

1. Insufficient disk space: If there is not enough disk space to write to the log file, the transaction will be unable to commit. This can happen when the disk is full or when the log file has reached its maximum size limit.
2. Log file corruption: If the log file becomes corrupted, it may prevent the transaction from committing. Corruption can occur due to hardware failures, software bugs, or other issues.
3. Disk failure: If there is a hardware failure on the disk where the log file is stored, such as a disk crash, the transaction may not be able to commit.
4. Long-running transactions: If a transaction takes too long to complete, it may cause the log file to grow too large, which can lead to an error. In some cases, the transaction may need to be optimized or broken down into smaller transactions to avoid this issue.

Solution

To resolve this error, you can take the following steps:

1. Check the available disk space and ensure that there is enough space to write to the log file.
2. Verify that the log file is not corrupted and that there are no disk failures.
3. Monitor and optimize long-running transactions to reduce the size of the log file.
4. Consider increasing the size of the log file or modifying the transaction to reduce the amount of data that needs to be written to the log.
