Hi,
This is an updated version of a posting made a couple of weeks ago after
some more testing.
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.
On Lubuntu 14.04 LTS

The 15.10 system ran with 4 cameras working fine for 24 hours. I then
added the 5th and it causes one camera to fail.
