Stuart Douglas commented on WFLY-7275:
--------------------------------------

I have submitted an XNIO pull request that should fix this. I think the problem is caused by the use of  CONNECTION_HIGH_WATER to control the max number of connections.

> Hi!
>  
> I have a JAX-RS application and after a lot of load, one thread eats up the CPU (100% usage) even when the load test app is terminated, and never drops down until I restart the app server.
> It causes me a lot of headeches because it totally makes the app server unusable until I restart, but the users unable to use the app in the meanwhile.
>  
> I'v attached the stack trace but I unfortunately don't see anything according to my knowledge.
> Please help me, I can provide more information if necessary.
