[cobbler] Error when starting cobbler under RHEL 6.3

When I start the cobblerd daemon, I see the following messages displayed on the console: # service cobblerd start Starting cobbler daemon: Traceback (most recent call last): File "/usr/bin/cobblerd", line 76, in main api = cobbler_api.BootAPI(is_cobblerd=True) File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 130, in __init__ self.deserialize() File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 898, in deserialize return self._config.deserialize() File "/usr/lib/python2.6/site-packages/cobbler/config.py", line 266, in deserialize raise CX("serializer: error loading collection %s. Check /etc/cobbler/modules.conf" % item.collection_type()) CX: 'serializer: error loading collection profile. Check /etc/cobbler/modules.conf' [ OK ] [root@local ~]# cobbler check cobblerd does not appear to be running/accessible This system is running RHEL 6.3, This issue was also happening under the 6.2, before I upgraded it to 6.3 I took a look at the modules.conf file and did not see any issues. Any ideas as to resolve this? Thomas Mackell
