Services

virt-who

This seems to be on by default in SLC6 but throws this error into /var/log/rhsm/rhsm.log every minute on every system we have:
2015-04-28 18:05:49,885 [ERROR]  @virtwho.py:133 - Error in communication with subscription manager, trying to recover:

It can be disabled with sudo chkconfig virt-who off

CCM

This is a cron task in the CERN openstack CC7 image. The task is defined in /etc/cron.d/ccm-fetch.cron as:
0 * * * * root (perl -e 'sleep rand 3600'; /usr/sbin/ccm-fetch) >>/var/log/ccm-fetch.log 2>&1

This dumps the following into /var/log/ccm-fetch.log:

LWP::Protocol::http::Socket: Bad hostname 'host.mydomain.org' at /usr/share/perl5/LWP/Protocol/http.pm line 51.

2015/04/30-17:57:39 [WARN] Retrieve: <http://host.mydomain.org/profiles/git-test.xml>: Can't connect to host.mydomain.org:80 (Bad hostname)
