In other words, an at(1) job.

sh, and not bash?  That could be the primary culprit.

It looks like you attempted to run code like this, in an at(1) job:

  something < <(dd if=...)

Only, one of two things prevented it from working as expected:

 1) You screwed up and wrote <<(dd if=...) instead of < <(dd if=...)
 2) You ran it under sh instead of bash.  E.g. by passing it directly
    to at(1) on a system where at(1) uses sh for its commands.

Um... they're your at(1) jobs, not ours.  I doubt anyone else has those
same jobs queued.
