org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [**] to the cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

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

cacheMaxSize

The maximum size of the static resource cache in kilobytes. If not specified, the default value is 10240 (10 megabytes). This value may be changed while the web application is running (e.g. via JMX). If the cache is using more memory than the new limit the cache will attempt to reduce in size over time to meet the new limit. If necessary, cacheObjectMaxSize will be reduced to ensure that it is no larger thancacheMaxSize/20.
