集成后，不定时在tomcat里报错

[myfreeway]

你好！集成apollo后，发现在tomcat里运行时，不定时的会报这个错误。现象是看到有tomcat进程，但是访问端口已经是404了。这是最后出现的日志。有什么建议吗？

几个应用放到一个tomcat里运行的。这几个应用都集成Apollo了。

这个是tomcat shutdown阶段的一个thread check，Apollo的线程都是daemon线程，所以没关系的。

至于那个报错是因为在shutdown阶段，线程执行的时候，一些class已经unload掉了，所以也是正常的。

先关闭了。

请问你最后怎么解决的？我现在也遇到这个问题了
