Greg, do you think WatchDog would be kicking in for the recent issues with Xojo Web apps not responding? I think you might be on to something there.
I have also been investigating this issue. When last we saw it occur, local requests to the server were failing to respond. We tried to curl http://127.0.0.1:9000 and got no response from the instance. The process was still running though, systemctl status theapp showed “active”.
I do like the idea of WatchDog, but because implementing it requires inserting code into the app itself I have been struggling with the idea of adding it to Lifeboat. I really appreciate the time you put into the example you posted …somewhere on here.
