Puppet master does not start

I've tried to start puppet master but I'm getting next error traces:

Ruby version is 1.8.7 and Puppet version is 3.3.1. Could someone give me any clue of what is happenning?

Thanks in advance,
regards

I realize that I had installed 2.6 version of puppet instead 3.3.1. It has been solved, I update previous version to 3.3.1. I;m still having same problem with new version. I paste here all details:

puppet.conf

    # The Puppet log directory.
    # The default value is '$vardir/log'.
    logdir = /var/log/puppet

    # Where Puppet PID files are kept.
    # The default value is '$vardir/run'.
    rundir = /var/run/puppet

    # Where SSL certificates are kept.
    # The default value is '$confdir/ssl'.
    ssldir = $vardir/ssl

    server=test.example.com

[master]
    certname=test.example.com

Why have you added the root user to the group puppet? puppetmaster
normally runs using the puppet user in the puppet group.

What groups is your 'puppet' user part of?

Here's mine:

# id puppet
uid=52(puppet) gid=52(puppet) groups=52(puppet)

Hi Sean,

updating the info, yesterday I removed root from puppet group and that is what I have now:

# id
uid=0(root) gid=0(root) groups=0(root)

# id root
uid=0(root) gid=0(root) groups=0(root)

# id puppet
uid=501(puppet) gid=503(puppet) groups=503(puppet)

And I getting the same error:

# /etc/init.d/puppetmaster start
Starting puppetmaster:                                     [FAILED]

# tail -f /var/log/messages

Somebody has any idea what is happening? Can I provide more information (logs, command, etc) where we can find what is the problem?

Thanks!!
