right, that's what I also thought and ask above about `RETRY_TIMES_OVER`.
Thank you for clarifying this.
How about this (flushing until data is available and `MAX_FLUSH_NUM` (which
can be quite large) is reached, and log warnings when cannot flush)?
```java
for (int i = 0; i < MAX_FLUSH_NUM && remainHowManyDataToFlush() > 0; i++) {
if (!CommitLog.this.mappedFileQueue.flush(0))
CommitLog.log.warn(this.getServiceName() + " service shutdown,
failed flush retried "
+ (i + 1) + " times");
}
CommitLog.log.info(this.getServiceName() + " service shutdown, all data is
flushed successfully");
```
