If that's the kernel that the "broken pipe" error happened on and you've
rebooted into that kernel then yes, it worked and I wouldn't worry.

The thing is that sometimes there's a race condition caused by the
scriptlet where it may be sending data to, say, a logger, then shuts the
logger down while some data is still waiting to be written. When that
last bit of data tries to hit the pipe, it gets a broken pipe error
because there's nothing on the other end of the pipe to receive it.
It's minor, but annoying (and scary if you've never seen it).

You'd see a similar error if, for example, you ssh to a remote server
and then the remote server shuts down (or at least kills the ssh
daemon). Any time you try to shove data down a pipe with nothing on the
far end to receive it, you'll get that error.
