because there was insufficient free space available after evicting expired cache entries

Tomcat运行的时候哗哗哗的报警告

版本是Tomcat 8.5.15

告警信息关键字如下

because there was insufficient free space available after evicting expired cache entries

只要在$CATALINA_BASE/conf/context.xml里增加资源最大可缓存的大小就行了，大小可按自己的需要定义

<Resources
    cachingAllowed="true"
    cacheMaxSize="100000"
/>

　　

 添加之后如下

重启Tomcat即可
