We're running puppet to manage our AWS instances and are migrating from a custom apt module for it, to the puppetlabs hosted apt module. Everything seems to work fine until during an puppet apply session, the puppet process will hang on %100 for as long as we let it.

I believe I've narrowed it down to puppet hanging while waiting for some "response" in the apt module, but I can't figure it out any further. I see a few related bugs and issues (like here http://projects.puppetlabs.com/issues/12185#note-27), but I can't find a good answer. Any help would be appreciated.

We're running puppet 2.7.20 on ubuntu 10.10. Puppet apt module version is 1.1.0.

As requested, here are the last few debug lines before the hang:

    debug: /Stage[main]/Kpython/Kpython::Pip_install[simplejson]/Exec[kpython_pip_install         simplejson]: Autorequiring File[/mnt/tmp]

    debug: /Stage[main]/Kvagrant/File[/usr/local/krux/components/kvagrant]: Autorequiring User[vagrant]

The next steps in this puppet run level should be apt module related.

This is the output of strace (with both ruby 1.8.7 and ruby 1.9.1):

         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
         rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0

  • Can you provide the output when --debug is added to the run?

  • Sure, although that would be an extremely long output, with nothing unusual before it just stops.

  • The idea is to find out what resource it stops on.

  • Agreed. However, I've been unable to do this. My thinking is that it's waiting for a response, but I can't find out from what.

    Do you have any files recursing a directory? serverfault.com/questions/324757/…. You might try running puppet under strace.

What ruby are you running? This feels something like this issue, which says it's FreeBSD but turned out to be a ruby issue.

  • Originally run with 1.8.7 but I've also tried it with ruby 1.9.1.
