Periodic "Exposure failed. Restarting exposure" when guiding with Lode was created by psjshep

I get the following message appearing in the status window of the Guide Tab in Ekos (kstars v3.1.0) - just every so often... sporadic... maybe 10 or 20 times in a single 1,200s exposure?

2019-02-04T22:35:09 Exposure failed. Restarting exposure...

My final images are 99% ok... but every so often there is a "bump" - not sure if it's directly related to the above or the aggressive guiding.

- I am using a Lodestar X2 guidecam, an Atik 16200, on a CEM60EC, running on an oDroid using Ubuntu 18.04.1 LTS
- libindi is compiled on the oDroid from a Git download v1.7.5 (according to the Changelog)
- Guiding is binned x2, exposure 1s, using a guiding accuracy of 1.2 (This works really well with the 60mm finder guider 450mm f/l)
- The Lodestar is plugged into the mount's guide port
- Guiding settings are :
Algorithm : Smart
Lost star timeout 60s
Max delta RMS : 10 arcsecs
dithering set on
