[Spacewalk-list] SpaceWalk/Cobblerd: ValueError: No JSON object could be decoded

[Bruce McAlister]

Hi All,

NOTE: I posted this message to the cobbler mailing list too, however, I 
wonder if it would be more appropriate here.


I am facing a strange issue after upgrading spacewalk from v2.2 to v2.3, 
I am having issues starting cobblerd which fails with the error message 
at the bottom of the mail:

I came accross the following reference at RHN, but since I am not a 
subscriber, I cannot view the solution:

https://access.redhat.com/solutions/184053

Has anyone come accross this, or can you offer any suggestions on where 
to look to debug this issue:


Starting cobbler daemon: Traceback (most recent call last):
