After a some digging, as I haven't seen this error before either, I found this thread: https://github.com/catkin/catkin_tool...
You can find an interesting discussion of what may be the cause for this issue:
The catkin internal make job-server runs out of job-tokens. Anyways at the very end of the thread, there is a suggestion is to reinstall to fresher version ofcatkin_toolsso perhaps try that.I am assuming you are not mixing Python 3 and Python 2 because that will also lead to unexpected behaviours.
Last resource, you can always add
global loadin thatserver.pyfile but I wouldn't recommend it.
