OVA Appliance - Cannot Log In No Graylog Server Available

[magurwara]

I did the initial configuration of password for admin and timezone. All services are running but cannot see anything on port 12900 and getting No Graylog Servers running... Checked server log /var/log/graylog/server/current and see "ERROR: org.graylog2.bootstrap.CmdLineTool - Invalid Configuraiton".

No idea why? Running in VMWare Workstation 7.1.3 on Windows 7 64-bit with 4GB allocated to the VM.

@magurwara Are there any other messages before or after the one you've mentioned? Ideally post the complete, unabridged server log.

[magurwara]

The log file is really big. It has 649,000 lines. Is there a way to upload it rather than copy the logs here?

[magurwara]

I think this bit of the log is repeating continuously. I set the indices to 10 and this may be causing problem.

This seems to be the culprit. There's some invalid numeric value in your configuration file.

Could you please post the configuration file (remove sensitive information like password_secret and root_password_sha2) or at least the line(s) you've changed? You can post it to https://gist.github.com/ and link the gist into this issue.
