The snapshot has been running for a couple days now without timing out. So that
seems to be working in the snapshot.
However, the original problem that caused me to start looking into this is
still there. I can't get resin 4.x to reliably serve media files, e.g. an mp3
file. This worked fine in 3.1.x.
The entry for mp3 in the app-default.xml is:
<mime-mapping extension=".mp3" mime-type="audio/mpeg"/>
Here is what the logs show when an attempt is made to access an mp3 file via a
browser:

A separate request, just for the header, using the curl -I command returns the
correct Content-Type and Content-Length and logs that same information in the
server log. But I don't see a reference to the Content-Type in the above
request (which was from a browser), and the Content-Length is only 3638 bytes.
Admittedly, I don't know exactly what resin is logging or why.
