CPU Spikes and Close-waits observed during increase of traffic
09:53 11 Nov 2025

We are observing CPU spikes upto 90% and increase in close-waits in our application with sudden increase in traffic. The traffic volume is not so high. Our application is java netty based. Also we have observed along with this behavior client requests are timing out. Application performance degraded due to the behavior. From Netty Threads point of view can you please help me understand if there is any issue with the inbound (read) /outbound (write) buffers config?
