我的环境是使用filebeat收集应用日志，上传到logstash-indexer，然后存入ES， filebeat版本是 1.3.1(amd64)，大概的配置是：
paths:
- /opt/mateinfo/logs/app/app.log
input_type: log
fields:
log_format: wfm_log4j
fields_under_root: true
ignore_older: 1m
close_older: 30m
document_type: app_log
因为发现日志盘空间变小，查了发现是filebeat没有释放日志文件句柄。我们是中间件是tomcat ,日志文件是50M，保存15个，业务量有时比较大，日志滚动很快。具体情况可以看下图，不知道有没有大神遇到过这种情况，是怎么解决的？
大神们帮看看，非常感谢。
