I am trying to debug some intermittent qvio server failure on a starling. When the starling boots up I get qvio overlay in voxl-portal just fine and then lose it after about 40s (my wifi connection disconnects). Everything comes back except qvio  overlay on voxl portal. 

When I manually run qvio server through adb it fails on 'waiting for imu'. I manually start voxl-imu-server and then run qvio server again with debug enabled and got the following: ![qvio_debg.png](https://forum.modalai.com/assets/uploads/files/1706219962919-qvio_debg.png) 
I can see qvio server is still connected as a client under voxl-imu-server:

I am clueless as to what is bringing down my connection and why qvio seems to be related to what is failing. This issue is intermittent and sometimes I am able to maintain qvio overlay in voxl portal. Sometimes qvio overlay will come back after a few min of being in a degraded state and not showing any stats on voxl portal.

To clarify the services all remain running when my connection gets hosed. I tried voxl-inspect-services and they all appear to be running whereas my wifi connection is what gets hosed (but recovers). When the disconnect happens I lose QGC mavlink to the starling and the streams go black. I ping the voxl IP and get nothing until the connection recovers
