Tomcat error: because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

See: https://stackoverflow.com/questions/58591273/what-is-the-correct-cache-size-to-prevent-tomcat-log-from-getting-flooded-with-c

 I am running Apache Tomcat/9.0.19 and recently I have noticed a lot of warning messages on the catalina.out log.

WARNING [main] org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [/WEB-INF/classes/static/maps/scripts/app-72be477367.js.map] to the cache for web application [##01] because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

WARNING [main] org.apache.catalina.webresources.Cache.getResource Unable to add the resource at [/WEB-INF/classes/static/maps/scripts/app-f223be6846.js.map] to the cache for web application [##01] because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

Adding the following line to the conf/context.xml solves this problem and my log is no longer flooded.

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