[jetty-dev] Many "Broken Pipe" exceptions on Jetty 9.4.12 - HTTP/2.0

[Michele Rossi <michele.rossi@xxxxxxxxx>]

hi all,

I am getting a lot of exceptions like the one below since upgrading to 9.4.12 on Java 10:

java.io.IOException: Broken pipe

Does this happen because people close their browsers?

Is there any way to make it less prominent in the logs?

If instead this indicates a more serious problem then I'd like to fix it properly.

Many thanks,

Michele
