graylog-server doesn’t start and the log output just shows this output and looks like it got stuck in loop

Hi @kvenkat971, any errors in server.log or syslog?

@kvenkat971
Hello,
I would like to ask a couple question.
Is it posible to see your server.conf file? Maybe execute this command.
`grep -v "^#" server.conf | grep -v "^$" | less`
Also any other configuration you have made while setting up your graylog server would be apperciated.The reason I’m asking about any confguration you made is because this doesnt look right.

Mine looks like this.
> 2021-03-25T18:25:41.439-05:00 INFO [CmdLineTool] Running with JVM arguments: -Xms2g -Xmx2g -XX:NewRatio
I’m assume at this point maybe there is a configuration error.
Thanks

Hi @gsmith
I have changed that setting but it still didn’t work. So I went for Graylog version 3 and it started fine.
I’ll close this for now and come back once I start testing version 4 again.
Thank you

Hi @dani,
Except for the one I have above, no errors were logged.
with the current settings it worked fine for version 3.
I’ll close this for now and come back once I start testing the version 4 again.
Thank you

I noticed the first line of your logs. It seems, that the airbus plugin was not yet released for 4.0, though there isn’t an exact error message indicating na issue with that
