Zwav Interface error

I have a Aeotec USD Stick 2 running under Indigo 7.3. in Mac OS 10.13.6. and I am getting the following error which I think is telling me communication with the Z Wave stick is being dropped waging I further imagine has to do with my old software Good guess??

This actually looks like your Indigo Server is getting hung up and not responding (or responding very slowly). Th e Z-Wave plugin is trying to communicate back to the Indigo Server but it is timing out.

How often are you getting this error? Are you noticing unresponsiveness from the Indigo Client (UI) app? I suspect if you had it open when this error occurred it would also be showing problems.

only apparently when I was trying to resynch my Aeotc Zw100 s.. after changing batteries... One died the other finally re-synched Message has not repeated in 12 hours. so just a 'glitch". Thanks
