kafka在使用过程中遇到的一个问题

[tur_test]

最近一段时间再根据@lizhitao 的博客学习使用kafka，并把它运用在我们的消息系统中，但是在消息系统实际运行中出现如下的问题
22:57:53,793 ERROR DefaultEventHandler:97 - Failed to collate messages by topic, partition due to: fetching topic metadata for topics [Set(pushMessage)] from broker [ArrayBuffer(id:0,host:10.160.1.212,port:9092)] failed

问题现象：当重启tomcat后，这个问题就不会出现，但是当系统运行了一段时间后，又会出现这样的问题，实在想不到是什么原因，向大家求教。

我启动了kafka后就解决了
