https://issues.apache.org/bugzilla/show_bug.cgi?id=50642 --- Comment #8 from Dennis Homann dennis.hom...@coremedia.com 2011-04-21 14:10:05 EDT --- The issue is still present in 6.0.32. In more than 50% of my attempts, the KeepAliveThread is not cleared correctly. Debugging and profiling showed that in these cases, the Thread object is still kept around, even though the thread was no longer active. In that case, ThreadGroup#enumerate does not even list it (WebappClassLoader#getThreads), although it's still shown in the profiler (YourKit in my case) and holds a reference to the WebappClassLoader. Even if it was listed by enumerate, WebappClassLoader#clearReferencesThreads would skip it as it is not alive. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- 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

https://issues.apache.org/bugzilla/show_bug.cgi?id=50642 --- Comment #2 from Mark Thomas ma...@apache.org 2011-01-27 08:41:35 EST --- Looking at the KeepAliveCache more closely, the currently solution is the wrong approach. Because the thread only exists for as long as it is needed and is re-created as necessary it has to be dealt with on web application stop. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- 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

https://issues.apache.org/bugzilla/show_bug.cgi?id=50642 --- Comment #1 from Christopher Schultz ch...@christopherschultz.net 2011-01-24 14:46:24 EST --- Could this be something that is done speculatively? I'm not sure HttpClient can be rigged to definitely launch it's thread during Tomcat startup, which is where the JreMemoryLeakPreventionListener does most of it's work. There is no URL to which we can guarantee a connection to succeed, unless we fire-up an HTTP connector just for this purpose. That could fail for ay number of reasons and just seems like confusion waiting to happen. The patch as it stands is somewhat fragile (no error checking, blindly using a Sun-specific class, etc.) but very understandable and could be implemented easily using something similar to the ThreadLocalLeakPreventionListener. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email --- 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
