Reasonly, we have updated our sqlite.data.dll version to 1.0.107. and now, we are experiencing "System.Data.SQLite.SQLiteLog.LogCallback: SQLite error (5): database is locked" several times in our trace log. (we have implemented the custom trace log listener). we close the every connection after it opens. Even though above log is written, database connection is open successfully and no exception is thrown. but we would like to know the reason behind it. Further more, we added Thread.Sleep(100); before call the connection.open() method and then we did not notice above error in our trace log. It seems sqllite take some time to release the sqlite file after connection is closed ? Questions: what is the reason for this error ? Can we ignore this error log ?

Do you know the SQL statement(s) that are causing this error to be logged? Are any exceptions being thrown?

This log, I have seen when calling connection.open() and no exception will be thrown.

Generally speaking, these types of log messages are harmless if no exception is seen by your code. However, I may be incorrect. If you show some C# sample code that demonstrates the issue, I can perform a more detailed analysis of the situation.

If we've determined that the messages are harmless for us. Is it possible to configure System.Data.SQLite to stop writing the error to our output?

If you are implementing a custom logging callback, you can perform custom filtering there; the default logging callback does not filter messages.
