So many mods. Hardly impossible to track root cause of bug. You can see for yourself that your level called 'Magicity' crashed. I assume that is the name of your main world. Also the reports mentioning LOTR birb entities may provide a clue that the LOTRmod may conflict with other mods with respect to entities. Which? Idk and I don't wanna know. I wish to refrain from trouble shooting cases of multi-mod servers crashing because of some potential incompatibility issue between the LOTRmod and one or more other mods.

Note that the JVM flag allocating memory indicates you only allocate 2G. That's a pretty low end server setup for such purpose. This may also be a simple case of 'memory overload' resulting in synchronicity issues. Not an expert guess though.
