Sorry for reviving such an old thread :"> I've actually hit this today on a single core machine (amd sempron if it matters..).

r...@testclient:~# ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]
r...@testclient:~# puppetd -V
0.25.1


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

Note too that the same bug should be affecting Debian testing and
unstable if the Ruby 1.8.7 p249 package is the problem.

Surely we have some people running Debian testing on the list? Seeing
any weird timeouts with execs?

I've reported this bug to Ubuntu.  The solution is to rebuild ruby1.8
without pthreads, unless ruby fixes the bug upstream which causes the
hang.

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.
ruby1.8 (1.8.7.174-2) unstable; urgency=medium
    [ akira yamada ]
    * Added debian/patches/090811_thread_and_select.dpatch: threads may hangup
      when IO.select called from two or more threads.
    * Added debian/patches/090812_finalizer_at_exit.dpatch: finalizers should be
      run at exit (Closes: #534241)
    * Added debian/patches/090812_class_clone_segv.dpatch: avoid segv when an
      object cloned.  (Closes: #533329)
