Frederic Soulier added a comment - 18/Mar/2016 7:48 PM Just installed Crowd 2.8.4 today and I ahve exactly the same issue as with 2.8.3 when stopping Crowd... CentOS release 6.7 (Final) 2.6.32-573.18.1.el6.x86_64 Using CATALINA_BASE: /home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat Using CATALINA_HOME: /home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat Using CATALINA_TMPDIR: /home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat/temp Using JRE_HOME: /home/crowd/java Using CLASSPATH: /home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat/bin/bootstrap.jar:/home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat/bin/tomcat-juli.jar Using CATALINA_PID: /home/crowd/Crowd/atlassian-crowd-2.8.4/apache-tomcat/work/catalina.pid Tomcat did not stop in time. PID file was not removed. To aid diagnostics a thread dump has been written to standard out. It's CentOS 6.x so no systemd.

William Rojas (Black Diamond) added a comment - 12/Nov/2015 6:32 PM Can someone comment on when 2.8,4 will go GA. We are encountering this issue and would like to get the fix ... Thanks
