I have a couple of cameras(3 of 18 total) that were working last week and are now offline after an update. They have multiple cameras defined at different resolutions and some resolutions are still working. There are frequent errors in the Log regarding them, Pasting a sample in:

Driveway_High is camera 26, Attic_low is 7, Attick2_low is 21
Is this a known bug, and if not what info would help to track it down?

Typically I would guess that signal 7 is not enough space in /dev/shm. Which makes me think this is a system upgraded from 1.34. Check your ImageBuffer Settings (Monitor->buffer->Image Buffer Count). It should be like 3. In the past it would be much higher, but it switched to MaxImageBuffer.

Hmm, assuming you mean "Image Buffer Size (frames) " then yes, my numbers were a lot higher than 3. And this was an upgrade from an earlier version, although I thought it was a 1.36 version. I'll try switching them all to 3 and see how that works. Thanks.

And all of my cameras are back to working now! Thanks again.
