Using WSJT-X, WSPR and losing TX RF output

First, let me say that WSJT-X is set up perfectly. If I use it in WSPR mode it works until it doesn't.

I have WSPR moving around on a schedule that matches the the solar day. I set it up, confirm it is working and walk away.

After a random interval the TX power goes to zero, no audio is delivered via DAX. This is easily followed by going back in time on WSPRNET until no one is hearing me on any frequency. I continue receiving stations (on display on WSJT-X and confirmed on WSPRNET).

I'm running WSJT-X 1.6, SmartSDR for Windows (1.9.2 alpha but this didn't matter, the same thing occurs on the last official release and all intervening alphas). The computer is a Gigabyte Brix with I7-4770 Haswell. CPU isn't a problem.

I run my computer and radio through a switch. It is necessary for my shack as the Brix doesn't have a second Ethernet port.

I'm concerned this says something about the resilience of DAX on a network, but I await hearing from others.

Piggy backing off Tim's comment above...

I have not found WSJT-X to be stable for extended periods of time when using WSPR, especially when band hopping is enabled. Maybe 12 hours max before the software hangs on me. This issue has persisted from 1.6 to 1.7 alpha (self compiled) to the publicly distributed 1.7 beta.
