I have stumbled upon the same issue, and it actually is a very big problem for R in general, as if you are developing models for production, lgb is one of the most useful libraries out there, and if you can not deploy it with Rserve, what else could one be using? Python!?
I believe RestRserve is a great contribution to the R ecosystem and the R community should pay more attention to productionizing models using R.

Seem it's LightGBM issue related with lightgbm:::Predictor$public_methods$predict which called from the lightgbm:::Booster$public_methods$predict.
Same here with lgb.save and lgb.load in the dummy_api_function.

I haven't had a chance to check your example yet. May be there is some
issue with forking - I believe lgbm use external pointers to internal C/C++
data structures. Have you tried to deploy it with RestRserve in
"cooperative" mode (this doesn't make fork for each request)? Also I
suggest to update Rserve to the latest version - 1.8.6 -
install.packages('Rserve',,'http://www.rforge.net/')

@dselivanov I confirm this issue with the Rserve 1.8.6. bst$predict hungs anyway even if dump the model load in the dummy_api_function.
