This is indeed a known problem. It crept into the system in the last update. It should be fixed in the next AIX update. Check with your SE to find out the availability date.

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. David Dick Software Innovations, Inc. [the Software Moving Company (sm)]
