If it fails after 110 every time, or around 110 it sound like a memory leak.

Just had a quick look at main.cpp

            char * value = new char [37];
            strcpy(value, data.c_str());
            mqtt.publish(pub_topic, value);

If you ever see a new without a delete in c++ it's a bad sign. I don't know how this library works but this probably isn't right.
