Hi,
For the second time in a week our Rational has gone down - and will not restart.
Which logs should I investigate to determine why the product went down in the first place.
I've looked into the "JazzTeamServer/tomcat/logs" directory. Under catalina.2013-09-03.log there are several errors such as those attached at the bottom of this message.
I think the errors below indicate there is a hung process (which is preventing the restart of CLM). What I am trying to work out is why it crashed in the first instance. Can anyone advise which logs I should be looking at? And what actions I should take to find the root cause of the initial crash.
Thanks,
Phil

LOGS : Any heapdump files in the <install_dir>/server directory ?
ccm.log (defined in <install_dir>/*/log4j.properties Make sure that the application is in fact down (not visible in a process listing). Since the "Address already in use" is showing, that indicates that there is some process still "running" which still is bound to the 9080 port. netstat -n -a |grep 9080 would confirm if you see something like: tcp 0 0 *.9080 *.* LISTEN in the netstat output. I've found that server.shutdown doesn't always bring the Tomcat down and sometimes it must be killed. |

Often times for us, there is still a running Java process that needs to be killed through task manager. Make sure it is every instance of Java as we often see more than 1.
