Hi,
This is without load balancer actually. I am directly sending to Tomcat.
Update:
A part issue I found was to be 9.0.29. I observed that when request were
timed out on client (2seconds), the client would send a RST frame. And the
GoAway from Tomcat was perhaps a bug. In 9.0.36, RST frame is replied with
a RST from Tomcat.
Now the next part to troubleshoot is why after about an hour or so,
requests are timed out at Tomcat.
Could close to 100 HTTP2 connections per second cause this on Tomcat?
Thanks
