> Key: FLUME-1644
> URL: https://issues.apache.org/jira/browse/FLUME-1644
> Project: Flume
> Issue Type: Bug
> Components: Channel
> Affects Versions: v1.2.0
> Reporter: Denny Ye
> Fix For: v1.3.0
>
>
> There have consuming failure at FileChannel and Flume didn't delete
> inactive/consumed log file any more. Thus, 'No space left on device' was
> happening.
> I want to raise another problem that in this case, there have too many log
> file with zero length. Flume holds so many file descriptors. Unluckily, Flume
> also creates log file every fixed minutes.
> Look at my storage folder in local of Flume.
