問題

Confluence is unable to startup. The catalina.out and atlassian-confluence.log both show the application starting up, but you never see a complete startup message.\

The following appears in the atlassian-confluence.log

2017-11-15 08:10:43,427 INFO [localhost-startStop-1] [com.atlassian.confluence.lifecycle] contextInitialized Starting Confluence 5.7 [build 5780  based on commit hash e911fdad641asdfca1ecd5a]
2017-11-15 08:10:45,467 INFO [localhost-startStop-1] [springframework.web.context.ContextLoader] initWebApplicationContext Root WebApplicationContext: initialization started

However, you never see the following message in the log:

2017-11-15 08:15:47,514 INFO [localhost-startStop-1] [com.atlassian.confluence.lifecycle] init Confluence is ready to serve
