This is something Andrew will have to comment on.

I know exactly what this one is.

Do you know what resource agent was running when this message came out?


What it means is that the main resource action (start, stop, etc) has 
finished, but that for some reason, a child process of that resource 
action is still running, and has not redirected its stdout/stderr to 
something else (like /dev/null), and it's still running.

Since the main process has died, we closed our end of the pipe, and if 
anyone else in one of these still-running child processes tries to write 
to their end of it in the future (like this child process which is still 
running), then it will not be able to, and will get a SIGPIPE signal 
which will likely kill it.

It is related to this bug:

The "right" system-wide fix for this problem is described here:

The observant will notice that this problem is not yet marked as fixed.
