I've had quite a few of these on my servers, from what I've gathered pretty much any interaction between Logistics Pipes and Thermal Expansion will cause a server crash, the way to resolve it is to remove the block listed in your crash-report which is here (36,55,193)
I usually use world edit from around 250-300 blocks away to destroy the block, but you could use MCedit or a similar tool if you know how.
Cheers
