problems when finetuning

[Ten000hours]

hi, when i run the code
GLOG_logtostderr=1 ../../build/tools/finetune_net.bin pascal_finetune_solver.prototxt ~/rcnn/data/caffe_nets/ilsvrc_2012_train_iter_310k 2>&1 | tee log.txt

the caffe net initailizition seems stopped suddenly,the log.txt shows like this
