[Puppet Users] Puppetmaster with stored configs leaks file descriptors on CentOS 5

Hi folks,

When I enabled stored configs on my puppet master, it began keeping lots
of open connections to the MySQL server (as far as I understand it
opened one connection for each client run and never closed them).

I set up the server to close idle connections after 5 minutes. Now the
database server does close the connections but the puppet master keeps
them in CLOSE_WAIT state and eventually runs out of file descriptors.

Here is a sample of the output of lsof on the puppet master:

.../...
puppetmas 16418 puppet  617u  IPv4            2683389               TCP
puppetmaster.ircam.fr:57097->mysql2.ircam.fr:mysql (CLOSE_WAIT)
puppetmas 16418 puppet  618u  IPv4            2683494               TCP
puppetmaster.ircam.fr:57099->mysql2.ircam.fr:mysql (CLOSE_WAIT)
puppetmas 16418 puppet  619u  IPv4            2683506               TCP
puppetmaster.ircam.fr:57100->mysql2.ircam.fr:mysql (CLOSE_WAIT)
puppetmas 16418 puppet  620u  IPv4            2684180               TCP
puppetmaster.ircam.fr:57108->mysql2.ircam.fr:mysql (CLOSE_WAIT)
puppetmas 16418 puppet  621u  IPv4            2683726               TCP
puppetmaster.ircam.fr:57102->mysql2.ircam.fr:mysql (CLOSE_WAIT)
.../...

The matching sockets don''t appear on the MySQL server.

The puppet master runs CentOS 5 with (pieces of) EPEL; here are the
installed versions of the relevant packages:

puppet-0.25.4-1.el5
puppet-server-0.25.4-1.el5
rubygem-activeresource-2.1.1-1.el5
rubygem-activesupport-2.1.1-2.el5
rubygem-activerecord-2.1.1-2.el5
rubygems-1.3.1-1.el5
rubygem-rails-2.1.1-2.el5
ruby-1.8.5-5.el5_4.8
ruby-mysql-2.7.3-1.el5

And the puppetmaster config :

[puppetmasterd]
    node_terminus = ldap
    ldapserver = nsldap.ircam.fr
    ldapbase = ou=Hosts,dc=ircam,dc=fr
    modulepath = /etc/puppet/modules:/usr/share/puppet:/var/lib/puppet/modules

    storeconfigs = true
    dbserver = mysql2.ircam.fr
    dbadapter = mysql
    dbname = XXXXXXXXXXXXXXXX
    dbuser = XXXXXXXXXXXXXXXX
    dbpassword = XXXXXXXXXXXXXXXXXXXXXXXXXXX

    reports = store,log,rrdgraph
    rrdgraph = true

Can you try with a newer rails/active record?
This one is a little bit old, and I''m not sure there aren''t
some bugs.
I vaguely remember that puppet required rails 2.2, but I might be wrong.

Will try. I was hoping I could get away with using whatever is in EPEL;
has anybody tested this kind of setup?

I ran into this same thing.  Update (rebuild) to the following rpms
versions from fedora 11:

rubygem-activerecord.noarch             1:2.3.2-4.fc11
rubygem-activesupport.noarch            1:2.3.2-2.fc11
rubygem-rack.noarch                     1.0.0-1.fc11

For various reasons, these versions cannot be pushed into EPEL.

Well, puppet 0.25 doesn''t refuse to run with rails 2.1 and 0.25 got
some patches to allow better support for 2.1, so it''s not completely
"unsupported" from a user perspective.  The wiki does list >= 2.2.2
for 0.25 and <= 2.2.2 for 0.24 though.

It''s definitely unfortunate that what is in EPEL suffers from this
bug.  I would love to see either puppet or rails there patched to work
around this.  I filed https://bugzilla.redhat.com/572722 for this
issue but haven''t heard anything back from the rails packagers yet.

There was a bug in the Puppet Labs redmine about these leaks, but I
think it was closed.  I need to find that bug again and reopen it.
