I can.
The LRM closed the pipe after the start operation completed. If there
were any child processes which were still running, their stdout/stderr
would be a pipe with no one to read from it -- ever.
If the service you started with the init script ever wrote even one line
to stdout after the start operation failed, that process would die with
SIGPIPE as the cause of death.
This message WAS CORRECT for the lrmd. We rewrote it to not close the
pipe until the other end closed the pipe in 2.0.8.
I'm pretty sure that the CENTOS people now have a 2.0.8 version.
