 Any other solutions to this and/or if it has been fixed in ubuntu?

 It hasn't been. I've been kept busy with other things unfortunately.

 Feel free to update the Ubuntu bug, or check with ruby upstream to see
 if anyone has reproduced it.

 The Timeout module is all pure Ruby, so it shouldn't be too hard to
 work out what is triggering this.

 fwiw, the MacPorts version of p249 doesn't have this issue, but it has
 a bunch of patches applied to it.

 http://svn.macports.org/repository/macports/trunk/dports/lang/ruby/files/

 I was planning to work through them and see what patch was resolving
 this, but am kind of strapped this week.

He's already uploaded it to Debian, so it will flow down to Ubuntu as

Joshua, I was just having issues reproducing it as well on a 4 core system.

As soon as I ran 3 instances of:

while : ; do openssl speed; done

to peg 3 of the cores, I could reproduce the same case as Kai initially posted.

   exec {TEST-EXEC :
   cwd = /tmp/,
   command =/usr/bin/touch /tmp/ /tmp/123 21,

 Joshua, I was just having issues reproducing it as well on a 4 core system.

 As soon as I ran 3 instances of:

 while : ; do openssl speed; done

 to peg 3 of the cores, I could reproduce the same case as Kai initially 
 posted.

               exec {TEST-EXEC :
                       cwd = /tmp/,
                       command =/usr/bin/touch /tmp/ /tmp/123 21,
                       timeout = 5,
                       logoutput= on_failure
               }

 puppet -v ~/test_exec.pp
 err: //Exec[TEST-EXEC]/returns: change from notrun to 0 failed:
 Command exceeded timeout at /root/test_exec.pp:6

ahah. cc'ing puppet-dev as they may have suggestions for the best way forward.

So this isn't a Puppet bug at all.

It looks to be a bug in the Ruby Timeout module that seems to be
triggered when most of your cores are busy.

I can reliably reproduce it by firing up openssl speed (n-1) times
where n is the number of cores and then using the Timeout module.

#!/usr/bin/ruby1.8
#

%x{/usr/bin/touch /tmp/}
puts executed without timeout ok

puts executing with timeout

require 'timeout'

status = Timeout::timeout(5) {
   %x{/usr/bin/touch /tmp/}
}

puts executed with timeout ok


which will produce something like:

r...@testhost:~# ps auxww|grep [o]penssl
root 22337 99.6  0.0  14616  2028 pts/6R15:04   2:52 openssl speed
root 22338 99.9  0.0  14616  2028 pts/6R15:04   2:49 openssl speed
root 22339  100  0.0  14616  2024 pts/6R15:04   2:49 openssl speed

r...@testhost:~# ~/tickle_ruby.rb
executed without timeout ok
executing with timeout
/usr/lib/ruby/1.8/timeout.rb:60: execution expired (Timeout::Error)
from /root/tickle_ruby.rb:11

r...@testhost:~# killall openssl
[1]   Terminated  openssl speed /dev/null
[2]-  Terminated  openssl speed /dev/null
[3]+  Terminated  openssl speed /dev/null

r...@testhost:~# ~/tickle_ruby.rb
executed without timeout ok
executing with timeout
executed with timeout ok

This looks to be a problem for all the ruby 1.8.7 p249 variants I've
tried, apart from the MacPorts one, which looks to have a bunch of
patches around these issues.

   What can I do ? Did i make a mistake, or is exec broken ?

   Kai, something is definitely broken in Lucid.

   We're seeing all sorts of process exec issues.

   Have you nailed this down at all?

  So Kai, we've been doing some experimenting here today, and have
  reproduced these hangs in all the Debian Ruby1.8 packages back to
  1.8.7.174-2.

  1.8.7.174-1 we've been unable to reproduce it on though.

  From the changelog I'm wondering if the first entry under 174-2 is
  responsible. Note this was later removed after upstream integrated it.
