 I am writing an app using Netty (4.1.16-Final), that after a while ends 
 up using 100% CPU (on multiple cores, in some cases).

 I used VisualVM to try get an idea what was going on, and it showed up 
 as being:

 io.netty.channel.nio.SelectedSelectionKeySetSelector.select() 

 I have attached a screenshot showing a more detailed trace.

 Any ideas what could be causing 
 SelectedSelectionKeySetSelector.select() to spin like this?

 Thanks!

 Rogan

So the real issue seems to be this one:

https://github.com/netty/netty/issues/7255

I'm using netty 4.1.22.Final on Linux (Ubuntu 16.04, OpenJDK 1.8.0_151).

Hi Nat,

Thanks for the pointer. It does sound quite similar!

I've experienced the problem on both OS X and Linux, but more prevalent on
OS X, I'd say. Next time it happens, I'll try put a breakpoint in that
method, and trace it to see what is happening.

Sounds similar to this issue: https://github.com/netty/netty/issues/2465 
Which platform is it? Linux version?
