Binti, It sounds like client were not able to connect due to instability on the server, and increasing networkTimeout gave them a better chance to join, but most likely they could not work properly anyway. Is I said, most likely this was caused by memory issues.
Any particular reason you're starting several nodes on each box. I would recommend to take a look at off-heap memory [1]. It will allow you to have only 4 nodes will small heap sizes (e.g., 4GB per node) and store all the data outside off-heap. In many cases it allows to solve memory issues easier.
