Additional info:
There is a Puppet-client running on the specified host.
I think that Puppet is doing something with ifconfig that triggers this problem.
Comment 1 Egon Kastelijn 2009-06-29 04:13:24 EDT
There are two other open bugs with the same title:
https://bugzilla.redhat.com/show_bug.cgi?id=508121 
https://bugzilla.redhat.com/show_bug.cgi?id=507103

They both talk about 'vpnc'.
On my system vpnc is not installed.
