Bug 2.4.2 upgrade from 2.3.5 crashes

[Mercury]

After replacing following files/folders:

config/
libraries/
modpack/
mods/
FTBServer-1.7.10-1614.jar version.json

FTB Infinity won't start anymore. crash_reportand fml-server-latest.log

e: Strange that same server setup is working under windows but not linux.

I actually explained this in my post under Tech Support:
The crash can be reproduced by placing a cable and a microblock in the same area. This will cause the cable to become a microblock (you can notice this because the ME cable will take longer to mine). Now even if you had removed the microblock itself the cable still remains a microblock and adding any Thaumic Energistics terminal (both arcane crafting and essentia terminals) will cause the same crash when this area become loaded or unloaded.

This is the problem you are having with this crash. What I suggest doing is checking the person who last logged in before the crash or checking the loaded chunks and checking for this and removing the blocks with mcedit or by removing the mod from your launcher and letting the blocks get removed.
