I'm using motion with mjpeg-streamer to record snapshots + motion pictures from 8 cameras on usb ports of a same computer (ubuntu 12.04 core 2 duo, 4Gb). It freezes completely the computer every once in a while (no X interaction possible, no ssh connection possible). It's quite cleat this happens only when handling the video recording system.
Using atop did not allow me to see any processus becoming wild. Memtest was ok with 7 runs. The only problem I see is that images saved by motion at the time of the freeze (last 30s, at 1fps) are of size 0, impossible to read.
Has anybody experimented this kind of problem?
Do you have ideas to investigate? A replacement of mjpeg-streamer to stream efficiently to motion in the same computer to test if the problems comes from it?
