gstreamer capture/encode: video4linux video6: Can't allocate memory for embedded data

I’m starting a third gstreamer capture/encode pipeline with two others
already running. Sometimes I get (in kernel output/dmesg)

video4linux video6: Can't allocate memory for embedded data

Any idea why this is happening?

Thanks, Cary
