Need help with server

[TheDean97]

I have taken a custom technic pack. http://www.technicpack.net/modpack/the-1710-pack.453902

And added AE2 stuff, RotaryCraft (with dragon API) and the server worked. I wanted to add Engineer's Toolbox.

And... I got an error.

That is the error log and full console log.

Thanks in advance

Add them in individually and see if each of them will work as the sole addition to the original pack. If they don't you have your culprit. If they do, then start adding them in sequentially until it fails and watch your logs. You will likely have a candidate culprit. Take out the last mod which made it crash and continue adding the others. If that works you definitely have your culprit. If it doesn't then multiple mods are having issues with the additions and you have your work cut out for you.

I am unable to provide additional recommendations because I am unwilling to try debugging a pack that large. Way too much hassle.
