Hello,
We run facter via cron on all hosts regularly for mcollective filtering
this is now hanging on 2.x.x (2.1, and 2.2 tried).
Facter run on various RHEL5 systems (both physical and virtual) hangs when
executed via cron.

Ruby Version
$ rpm -q --qf '%{VERSION}-%{RELEASE}\n' ruby
1.8.7.370-1.el5
This didn’t happen with 1.6.x which was our previous version.And I cannot
find a RHEL6 host with this issue. So I suspect Ruby here. Any ideas anyone
?
Thanks
Paul
