My backend just aborted and my wife isn't happy because it didn't
record Medium. There were 14 mythbackend --generate-preview 0x0
processes running. I've had this problem of lots of
--generate-preview processes since upgrading to .22-fixes though I
usually see it as mythcomflag stops working. Can anyone help me
figure out why I am having this issue? Here is the mythbackend log:

I would greatly appreciate any help someone could give. I compiled as
I always have and never had this problem with .21-fixes.
Thanks,
