--- Comment #2 from joe.stepow...@gmail.com --- Hi Mark I have been able to pinpoint that the issue started with 8.5.3. 8.5.2 seems to be ok. I can see from the 8.5.3 changlog at least one change around sockets: "Fix a cause of multiple attempts to close the same socket" I downloaded, built and deployed the sample Spring Boot app from one of the tutorials. Couldn't reproduce the issue, even with 8.5.4, although the app is pretty "dumb": https://spring.io/guides/gs/spring-boot/ https://github.com/spring-guides/gs-spring-boot/archive/master.zip Users connect to our app over https, and our app connects to ldap over http and other webservices over https. No WebSocket, Servlet 3.0 Async or Servlet 3.1 non-blocking.
