Hi all,

I have an application team occasionally getting the following exception with 
their application. They are currently using Tomcat 9.0.56. I'm not finding much 
on the intertubes in regards to this. Does anyone have any information?

org.apache.tomcat.util.net.Acceptor run
SEVERE: Socket accept failed
java.io.IOException: Duplicate accept detected. This is a known OS bug. Please 
consider reporting that you are affected: 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924298

That bug and the Java issue linked from it should answer most questions. The linked Spring bug is generally interesting but doesn't shed much light on this issue.

What do you want to know that they don't address?

Mark
