Can it be repeated:
Just use pregenspawn with a large enough value to have it create the entities in question.

Known Fix:

 

[mti_]

I experienced errors while doing pregen.
What fixed it for me is have the server idle for a minute or two after generating the world in the first place and once TPS have calmed down a bit I could pregen w/o getting any errors. It was railcraft oil being the problem tho.
(Also I have noticed that volcanos can sometimes only spawn in one half when pregen'd)

Sounds like your server may have a weak CPU and is under a lot of stress during pregen causing volcanoes to not generate properly.
