Hello everyone
Just recently got my local server running (thanks Gunner).
i left it run overnight, and seemed fine, but then when i started to interact with it, locked up, and since has been unresponsive, working intermittently, not at all sometimes, etc.
I am using server-0.36.0, java 10 and a Mega 2560 with USB Serial link. I have simplified my code (and re-ran it to ensure the problem still exists) as shown below.
That said, I do think it is something related with the server. The code (full version) seemed to work fine with blynk cloud - but switched to local for latency / internet dependability reasons.
The blynk logs don’t seem to tell much, I can provide anytime. I should ask though, would the “best place to look” be in the blynk / postgres / stats / worker files? stats seems to have the most in it, but I am not sure how to use it in this case?
Appreciate your time in advance, thanks!

requiring me to make timing adjustments for the added latency of WiFi… go figure… but then it is wired vs. wireless.
Just not fully functional with Java10 (which is why I was asking)… still best to stick with Java8 for the RPis for now.
