This may or may not be related to why I am having so many authentication problems, but I believe it needs its own thread…My setup as follows:-Windows Server 2008 R2-Alfresco Communty 3.2r2-JDK 6u18 (x64)-Tomcat 6.0.24 (x64) w/ ARP dlls-JVM Confguration: -Dcatalina.base=D:\Alfresco\tomcat -Dcatalina.home=D:\Alfresco\tomcat -Djava.endorsed.dirs=D:\Alfresco\tomcat\endorsed -Djava.io.tmpdir=D:\Alfresco\tomcat\temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=D:\Alfresco\tomcat\conf\logging.properties -Dalfresco.home=D:\Alfresco -Dcom.sun.management.jmxremote=true -XX:PermSize=128m -XX:MaxPermSize=256m -XX:ReservedCodeCacheSize=64m -Xcomp -Xbatch -Xms2048m -Xmx3072m -Xss1024k
Any attempt at authentication causes a locks up the java process. Having checked JConsole with the Topthread plugin I have narrowed it down to the SESS_W0_LSN1 (where the 0 & 1 can vary) series of threads. If I try to authenticate again, another thread is created and it locks up (uses 100% CPU). It seems to happen whether I am connecting via CIFS or Webdav, or Alfresco Explorer.I have had this same issue with inbuilt NTLM and Passthru authentication. It happens whether I'm on a machine which I don't have authentication issues (i.e. XP, Server 2003) or otherwise (Vista, 7, Server 2008)An example of the thread info from JConsole is as follows:Name: Sess_W0_LSN1

When shut down the server I get these sorts of errors (among others):
SEVERE: A web application created a ThreadLocal with key of type [org.alfresco.repo.security.authentication.AuthenticationUtil.ThreadLocalStack] (value [org.alfresco.repo.security.authentication.AuthenticationUtil$ThreadLocalStack@1cad68c5]) and a value of type [java.util.Stack] (value [[]]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.

What should I do? Is this an Alfresco or JVM bug?
