Apologies if this has been asked before. We have migrated from an older version of Jira to 7.12 on Centos 7 (have also tried Ubuntu 16/18). The installation runs perfectly, the application is accessible and we are able to do a restore from xml. However, if we restart the application via rebooting the server or via the scripts, it stops listening. It seems from ps -ef that the application has loaded and there are no errors in catalina.out - but netstat -nlpt reports that there are no applications listening on 8080 (tcp or tcp6). Have tried the install many times. Any guidance appreciated.
