I am running a Motion 3.2.12 CCTV system on Lubuntu 14.04 and 15.10 with an 8 channel tw68 card. I have 6 camera attached. When I activate more that 4 threads in motion CCTV application one or more threads continually timeout. With any 4 cameras of the 6 cameras active it seems stable. I have been running this system with 6 camera on Lubuntu 12.10 for over 3 years without a problem.
