Has it completed any iterations? Has it finished loading the data, and started building the model? How many users and how many items do you have? How many factors are you trying to extract?
Have you seen a message like this one:
[INFO ] 2016-08-02 09:18:17,810 -- Dataset: ./train_strings.txt
[DEBUG] 2016-08-02 09:18:23,331 -- With Specs: {Users, Items, Ratings} = {88715, 8577, 1864230}, Scale = {1.0,5.0,10.0,15.0}

Can you post your stacktrace?
from librec.
just add more Xmx memory to figure out this problem. -Xmx6144m is needed for 600m data ( about 10x space for data in Java), I think. You can try it.
