Thanks for the report. The message is just informational and designed to reveal the cases in which this happens. I have to say that I didn't expect anyone to leave a multi-process pipeline suspended for a week and trigger it. The original motivation for the message was to figure out how big the pid-reuse problem was after a discussion started by http://lists.gnu.org/archive/html/bug-bash/2012-07/msg00054.html That's where you see the Posix requirement that shells save the exit status of the last CHILD_MAX processes. Bash does the right thing; it zeroes out the saved pid information.
