The problem occurs - I think - with the Exim mta under RHL9 as well. The error/warning states that a child process was started, and whilst the parent waits for the child it has set the SIGCHLD signal set to ignore (SIG_IGN). In that respect it is sort of saying the parent is waiting for the child but it has also told the system to ignore it - so why wait for it? I would not be overly concerned about it - the code author(s) - Shaun and Robert - will have decided what is best for the parent/child processes. If you have mentioned it on the BB list then there is not much more you can do about it.
