Just output two diffrent log message in one line. Message has been output to file but in wrong format. Here is the log file content example:  Maybe two diffrent worker flush each log message to file at the same time, and log message size is larger then log cache buffer. Perhaps it happens like this: message A's size is larger than the cache size, so part of message flush to file, then message B in another worker begin to flush. After that message A continue flush its remained message. So I think we need concurrency control when file-logger flush to file. 这里file-logger并没有执行报错， 正式将两个不通的日志混合在一行输出了，造成日志格式错误。相面是我得到的日志截图（对敏感数据进行了处理）。 我猜测发生过程是这样的： 一个工作进程将日志A的消息内容超过了用来缓存消息的buffer，当A开始向文件flush时，首先将前半部分内容flush到文件中。此时另一个工作进程开始将日志B向文件flush。最后将日志A的剩余消息写入到文件中。 因此，我们认为在file-logger在向文件写数据的时候需要并发控制逻辑。 -- This is an automated message from the Apache Git Service.
