Bus error when training until iteration 4110

[Nestarneal]

Hi,
I try to reproduce your results in the repository Realtime_Multi-Person_Pose_Estimation, and I follow the Training Steps in README to download the LMDB data and this repository for training.

I've tried three times for training, but each time when the iteration reaches 4110, I always get the following error:

I1031 21:17:26.459512 32355 sgd_solver.cpp:106] Iteration 4110, lr = 2e-05

Bus error

I create a script for training, and its contents are as following:

#!/usr/bin/env sh
/path/to/caffe.bin train --solver=pose_solver.prototxt --gpu=1 --weights=../../../model/vgg/VGG_ILSVRC_19_layers.caffemodel 2>&1 | tee output/$(date +%y%m%d_%H%M).txt 

Do you have any idea about this?

Many thanks.
