--- Comment #5 from Stefan Frings <stefan_fri...@qvc.com> --- Enabling FINEST logging for org.apache.catalina.core did not gave any helpful message. I still dont see any warning or error message in any logfile. But I have some few more debug messages now. I managed tro track the event handling and did not find any problem there. Lifecycle.CONFIGURE_START_EVENT and Lifecycle.CONFIGURE_STOP_EVENT are both completely processed by NamingContextLister without exception. Also the ContextAccessController removes the securityToken properly from the hashmap when I stop the program. So what I saw today does not match the heap dump that I created a few days ago. Sorry for that, I must have done something wrong without noticing it by myself. I attached a new screenshot from heap dump analysis, which looks much smaller now. And I see now totally other classes holding references to the classloader. But these classes are again all part of Tomcat or JVM, am I right? How can I analyze that further? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
