1400 is a lot, maybe there's a maximum number of features, such as 1024.

I tried 600 features(600 fields),segment fault too
x fields means there are dim*x*x interactions, that's quite a lot of features. You'd better reduce your fields, or maybe you should use features other than fields
training data num: 400000, feature num: 1400
same data, use FM is ok. but use FFM , segment fault when init. if Use data num 80000, and feature num 300, is ok.
its my config: ./xlearn_train ${pre}.${train_tag}.${suf} \ -s 2 \ -v ${pre}.${valid_tag}.${suf} \ -x auc \ -p adagrad \ -r 0.1 \ -b 0.0002 \ -k 4 \ -u 0.66 \ -e 100 \ -sw 10 \ -nthread 16 \
SO, how many num of feature that xlearn-ffm can support?
