我有一个多线程应用程序，我想使用boost-log。我用的是boost 1.81
要记录我使用宏
BOOST_LOG_TRIVIAL
在这里我配置boost-log：

logging::register_simple_formatter_factory<logging::trivial::severity_level, char>("Severity");
logging::register_simple_filter_factory<logging::trivial::severity_level, char>("Severity");

std::ifstream file("log.config");
logging::init_from_stream(file);
logging::add_common_attributes();

下面是log.config的内容：

[Core]
DisableLogging=false
#Filter="%Severity% > info"

# Sink settings sections
[Sinks.File]
# Sink destination type
Destination=TextFile

# Sink-specific filter. Optional, by default no filter is applied.
Filter="%Severity% > trace"

# Formatter string. Optional, by default only log record message text is written.
Format="[%TimeStamp%] %Message%"

FileName="Log_%d%m%y_%3N.log"
Target="logs"

RotationSize= 5242880 # 5MB

# The flag shows whether the sink should be asynchronous
Asynchronous=false

# Enables automatic stream flush after each log record.
AutoFlush=true

输出日志文件包含损坏的行或截断/重叠的行，如下所示：

我怎样才能实现一个日志文件没有这些问题？
我假设boost会处理并发，有办法启用它吗？
