There are two issues here: 1. These error messages occur even during normal channel shutdown, because that's tracked in the mozilla::ipc::MessageChannel layer, which the ipc/chromium code can't access. 2. If we get this kind of error when the channel wasn't intentionally closed, it almost certainly means that the other process crashed. In that case, having error messages from a different process and a likely unrelated subsystem just leads to confusion and misfiled bugs. (Also complicating things: on Unix a closed channel often, but not always, results in an end-of-file indication, which already isn't logged; on Windows it's always a broken pipe error, which causes a much larger amount of log spam.) Bonus fix: the error that contains a fd number is clarified to avoid having it mistaken for an error code.
