Bug ID: 57265
Summary: Tomcat 8 hiden behind NGINX fails to send file when
using NIO connector
Product: Tomcat 8
Version: 8.0.15
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: Connectors
Assignee: dev@tomcat.apache.org
Reporter: jaros...@kamenik.cz
We have moved Tomcat 8 server behind the nginx balancing server and have
started experiencing this problem:
org.apache.tomcat.util.net.NioEndpoint$NioBufferHandler@2001a157
26-Nov-2014 11:37:04.476 SEVERE [http-nio-8443-ClientPoller-0]
org.apache.tomcat.util.net.NioEndpoint$Poller.processSendfile
java.lang.IllegalArgumentException: You can only read using the application
read buffer provided by the handler.

Problem occurres irregularly when loading lots of scripts refencenced by
homepage.
It seems to be ok with useSendfile=false. I have tried to add some slow logging
(with flushing output) to code and it lowers occurrence rate, so it looks like
some race condition problem.
