I’ll continue testing over the next couple of days. I got some errors, but because the system ran out of file descriptors (I bombed the system with requests). I also saw a Killed error somewhere, so I suspect the problem persists.
I will continue testing in different system conditions, such as high memory usage and long uptime (lots of hot reloads from Phoenix, for example) and report back. I’m still wondering what caused the problem, or if I can prove the connection pooling caused it definitively.
I think I’ve seen the problem more with long-running instances of mix phx.server, which include closing the laptop lots and leaving the process on for days on end.
