Cant start confluence and connect through browser:8090

[Oliver Dalton]

Our server hung so we restarted the service /etc/init.d/confluence restart and it never can back.  see: (catalina.out log)  https://pastebin.com/NRahtGCz

We are running the standalone server on Opensuse on a VM with 4 cpu 12gb ram 60gb hss, and the default config 8090 with the context path "" with a Postgres DB.  

The service says that the confluence has started ok, but the browser never connects to the IP:PORT.

Hi Oliver,

You may take a look at below article for the issue you're experiencing with;

https://confluence.atlassian.com/confkb/confluence-logs-errors-this-prevents-creation-of-a-guid-due-to-incorrect-host-name-235668247.html

Typically, you will need to add the hostname to /etc/hosts file on the server with IP address.

thanks

HI Shankar, 

Thank you for the response.

The /etc/hosts file does contain the hostname and IP address of the server.

As I said the server had been running fine, then just hung and wouldn't restart the service instead deciding to throw lots of Java errors.

I managed to get this working again by using these CMDs.

ps -ef | grep confluence

ps -ef | grep postgres - (we are using postgres)

It seemed that a PostgreSQL process had remained open and was preventing the confluence service from to fully starting.

I had a look at the "atlassian-confluence.log" @ /var/atlassian/application-data/confluence/logs but I couldn't see any useful information here.

I found the "catalina.out" @ /opt/atlassian/confluence/logs had information about confluence not starting.

This cmd ps -ef | grep Postgres showed that a Postgres process was running and killing this allowed the service to restart successfully.

When the server starts up correctly you should see in the "atlassian-confluence.log".
