Re: Cannot upgrade past Tomcat 6 due to massive memory increase

others will agree, but if Tomcat had the option to ignore META-INF/resources in JAR files, you could probably save some memory. Since you are currently using Tomcat 6, this setting wouldn't affect you at all, since Tomcat 6 didn't expose those files in the way Mark describes. On the other hand,

Re: Cannot upgrade past Tomcat 6 due to massive memory increase

to JAR scanning (tomcat.util.scan.DefaultJarScanner). When setting jarsToSkip=*, the memory consumption was decreased to something somewhat more reasonable (2-3x increase over Tomcat 6) and the startup time went back to what we were used to with Tomcat 6. However at that time we opted to stay on Tomcat

Cannot upgrade past Tomcat 6 due to massive memory increase

Summary: Because of our use case (hundreds of webapps per instance), we cannot feasibly upgrade our Tomcat 6 containers to Tomcat 7 or Tomcat 8, due to the massive increase in memory the upgrade causes. Background: We’ve been running Tomcat 6 for several years, on perhaps an unusual scale
