Question

My C#/SQLite app works fine but outputs this error once in a while:

SQLite error (10): delayed 25ms for lock/sharing conflict

As suggested on this thread, I updated to the latest SQLite, but it still happens.
How to fix this?

From this original code:

    using (var command = new SQLiteCommand(GetSQLiteConnection()))
    {
        try
        {
            command.CommandText =
                "DELETE FROM folders WHERE path='" + path + "'";
            command.ExecuteNonQuery();
        }
        catch (SQLiteException e)
        {
            SparkleLogger.LogInfo("CmisDatabase", e.Message);
        }
    }

Changing to this solved the problem (only the first two lines differ):

    var connection = GetSQLiteConnection();
    using (var command = new SQLiteCommand(connection))
    {
    try
        {
            command.CommandText =
                "DELETE FROM folders WHERE path='" + path + "'";
            command.ExecuteNonQuery();
        }
        catch (SQLiteException e)
        {
            SparkleLogger.LogInfo("CmisDatabase", e.Message);
        }
    }
