Did the master became unresponsive as well? If so, any messages
from the master process?
You may want to try out following:
send a PIPE sig via kill to a child process
after that, try to telnet to 12525 if you get a connection
then things "should" be ok.
If not, then I have to rethink about signal trapping and signal
logging. It works here, on a FBSD, gentoo (kern 2.6) and redhat 7.1 (kern 2.4)
Which wouldn't explain why the children got a SIGPIPE, though.

Unfortunately not. It doesn't tell why the children received
SIGPIPE. It doesn't appear to be reproduceable either.
