Hi
I don't really know how to describe the situation. After a certain load and
time (around 1 h) our application "freezes". This only happens under macOS.
The resulting pattern shown in the attached screenshot builds up over time,
where one thread after the other becomes like this until the freeze. When
running inside a docker container based on "openjdk:8-jdk-slim" everything
works fine. There I don't see the pattern emerging.
Does maybe anybody know what could be causing the lock-up? I don't really
understand the thread dump, but maybe someone with deeper knowledge
of akka-http can maybe give me a hint? In this particular scenario, we are
extensively using the akka-http client to connect to an external service.
Versions:
akka: 2.5.13
akka-http: 10.1.3
Java: 1.8.0_161
Screenshot and thread dump from YourKit are attached.
Cheers,
Ivan
