aborting during step 4

[dk379]

I just run CycleHunter (on FreeBSD) against com.ua zone file and got this:

$ python CycleHunter.py --zonefile com.ua/zone --origin com.ua. --save-file com.ua/hunt --base-dir com.ua --workers 8

the zone file length is just over 1.5M lines:
$ wc -l com.ua/zone

Trying on a smaller zone, still aborts, but with different error:

note -- perhaps the --origin should be using kiev.ua or is .kiev.ua needed? I found it strange...

so again, failure on step 4 (or step 8?)
