The EMT, also known as Tomcat, service shows that it is running, but port 8543 is not listening for connections. This causes issues with functions such as: Proxy deployment manager Snapshot manager RabbitMQ DTLT Topology manager Connection manager Restarting Tomcat, as shown below, does not resolve the behavior. emwebapp . sh --stop emwebapp . sh --start Port 8543 is not listening and reports "connection refused". admin@ave:/home/admin/>: curl -v localhost:8543 * About to connect() to localhost port 8543 (#0) * Trying ::1... Connection refused * Trying 127.0.0.1... Connection refused * couldn't connect to host * Closing connection #0 curl: (7) couldn't connect to host
In the mcserver.log* files: /usr/local/avamar/var/mc/server_log/mcserver.log.0 We see that the log reports connections refused to port 8543 WARNING: Failed (https : //localhost : 8543/deploymanager/auth/logout)(attempt 2 of 3): Connect to localhost:8543 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused (Connection refused) 11/04-20:11:37.00805 [RMI TCP Connection(1204)-10.80.209.10#9026] com.avamar.mc.pdm.ProxyDeploymentManagerService.submitJsonWithRetry The catalina.out log contains everything that is written to Tomcat's system.out and system.err /usr/local/avamar-tomcat/logs/catalina.out The catalina.out file comes from the catalina . sh script that is conventionally used to launch Tomcat. Whenever tomcat does not launch properly, or something is wrong with the Java implementation of tomcat, look at catalina.out In this case, the output includes: 2022-11-08 20:41:13.866 ERROR 21323 --- [ost-startStop-1] o.s.boot.SpringApplication : Application run failedjava.io.FileNotFoundException: /home/admin/.keystore (Permission denied) Root Cause /home/admin/.keystore ownership was root:root.
