使用gelf收集日志，并输出到kafka，现在运行一段时间就挂掉在日志中出现了ERROR级别的日志,分析了hprof发现还剩余很多内存。总共128M用了40M，剩余80M
（1）先出现3条：logstash.inputs.gelf JSON parse failure.Falling back to plain-text 'Exception:Failed to decode data:Java heap space'
（2）紧接着：报了一个ArrayIndexOutBoundsException: Index -1 out of bounds for length 20
（3）下面是好多：Exception in pipelineworker,the pipeline stopped processing new events,please check you filter configuration and restart Logstash.IllegalStateException:cannot perform operation after producer has been closed.

另外128M heap太小了，增加heap至少可以缓解这个问题。
