--- Comment #11 from Dan Armstrong <supp...@aoindustries.com> --- I have submitted a fix to this issue via a pull request on the github copy of the source for both Tomcat 7 and Tomcat 8. Please merged these into the main Tomcat source repositories. Lock contention alleviated via concurrent maps, while still maintaining the necessary weak keys. https://github.com/apache/tomcat70/pull/11 https://github.com/apache/tomcat85/pull/5 Please also check if the Tomcat 9 in development has the same implementation based on WeakHashMap. It is a serious point of lock contention under heavy concurrency. -- 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
