[mythtv] Smolt down ?

[Peter Bennett]

Hi Stuart

I have an extremely slow shut down of mythfrontend and I was blaming the 
new purge of cache for it, but I think it is smolt causing the problem.

This takes 120 seconds to fail:

/usr/share/mythtv/hardwareprofile/sendProfile.py --submitOnly -a
Processing MythTV Data
Error contacting Server: [Errno 14] PYCURL ERROR 22 - "The requested URL 
returned error: 504 Gateway Time-out"
Could not send - Exiting

Also trying to browse http://smolt.mythtv.org gives no response

On exiting mythfrontend I see a long wait with the frontend stuck on the 
"are you sure you want to exit" message, before this comes into the log
2017-10-19 16:56:19.077251 I  HouseKeeperTask 'HardwareProfiler' Failed.
Then shutdown completes
