I, too, have seen this problem.  It has something to do with
job control.  For some reason some process has been "backgrounded"
and tries to write to its stdout, which gets trapped to produce
the error message.  At least, this is my guess.  I get around
it by killing the backgrounded process(es).

The intermittence is peculiar.
