Hi,
for me this usually fails w/ out-of-memory, and then likely no memory is
available
to fork and run new processes anyway. We could certainly try to handle
non zero exist status and properly error out there for a maybe 50/50 chance
some stuff can still run? Especially in your case of unsupported format, …
maybe I try add handle that live this lunch break ;-)
Bonne journée,
René
