Issue #7141 has been updated by Dominic Cleal.
In case anybody else finds this issue, Red Hat released the following errata for RHEL 5.7 containing the fix: http://rhn.redhat.com/errata/RHSA-2012-0007.html The minimum kernel version for the fix is kernel-2.6.18-274.15.1.el5. I think the bug has only been reported in the EL5 kernels, not EL6. ---------------------------------------- Bug #7141: puppetd runs fail in 'daemon' mode when stat'ing /proc files https://projects.puppetlabs.com/issues/7141 Author: Matt Wise Status: Closed Priority: High Assignee: Category: file Target version: 2.6.x Affected Puppet version: 2.6.5 Keywords: Branch: I accidentally had a tree that Puppet was watching (auditing) with a few files that pointed to the /proc filesystem. Manual puppet runs worked perfectly, but background 'daemon' runs would hang. After a bit of stracing, I found that the hang started as soon as the puppet process tried to look at these /proc symlinked files. Again, manual puppet runs worked perfectly, but the daemon background runs are the ones that failed. Removing the symlinks solves the problem, but this is a bug of some kind.. I'm just not sure where.
