2017/06/05-14:57:07 [INFO] Profile updated, new latest CID 1 name [redacted]

So CCM goes from a CID of 20 to mentioning 0 but actually creates profile.1.

This is happening during boot so ncm-cdispd comes up and crashes because of an invalid CID:

2017/06/05-14:57:05 [INFO] ncm-cdispd version 16.12.0 started by root at: Mon Jun  5 14:57:05 2017 pid: 983
2017/06/05-14:57:05 [INFO] initalization of components
2017/06/05-14:57:05 [ERROR] fatal exception:
2017/06/05-14:57:05 [ERROR] CID '' must be a number
2017/06/05-14:57:05 [ERROR] exiting ncm-cdispd...

I see a reference to CIDs being 0 requiring a unit test change so was this a known bug in 16.12 that was fixed later?

This is RHEL7, running 16.12 of ccm and ncm-cdispd.

@ned21 odd thing number one: going from cid 20 to 0. was there a ccm-purge that left some files lying around?

the changes in the unittests were not related to any bugs, they are related to https://github.com/quattor/maven-tools/pull/160/commits/5bb90a3cdf27842700dd4b48413fe27b9f525b8b (for some reason, the unittest CID started at 1 instead of 0)
