 A customer (thedod) sent me an incident report file. It turned out to be
 triggered by this:
 {{{

 }}}
 I'm pretty sure there's nothing out of the ordinary about this. It's just
 what happens whenever a network connection to a storage server fails
 during an operation. Is that right?

 So I'm asking the customer to look for ''other'' incident report files to
 send to me. But if this was a false alarm, then it has impeded our
 investigation and should be silenced.

 Assigning to Brian to confirm my understanding that this is common and
 harmless.
