   I'm afraid that by fixing the memory issue with the optimizer using executors, it has broken the optimizer update on kvstore. I think there should be a way to way to fix this in the R-package/src/kvstore.h/cc. 
   In the meantime, could you try using "local_allreduce_cpu" or "local_allreduce_device" instead of "device" for the kvstore parameter?
