This also happens with the new Direwolf20 Pack, several threads about this one, seems serious...

As pointed out by someone else:- http://forum.feed-the-beast.com/threads/forestry-server-crash-mindcrack-v7.6845/#post-79292

 

[ramdor]

same here, draws the chunk I am in then same error

EDIT

I can confirm that changing the forestry common.conf file outlined in the thread above fixes the issues. Not sure what impact this will have going into the future by leaving this true however.

 

[Maik Kellerhals]

Yes, this fixes it! (see above)

 

[dragonfire2876]

thanks for the info however this does not seem to fix the problem any other help will be loved

 

[dragonfire2876]

:S still no fix

 

[glasspelican]

So you set Both of the config options to True and you still have the problem?
your sure its the same crash?

Note this crash has nothing to do with machines its a bug in the new tree breading system in forestry
