Hi folks, I have a async response which is designed to run as long as the browser is connected (using SSE). After the browser disconnects and data is written to the response internally a "IOException: Broken Pipe" is thrown, which itself is not logged, but there is some error from the state handling logged (see below) which is quite noisy. Is there somehow to prevent this from happening? or is this a bug?
(also happens with tomcat 9.0.27) The spring boot guys also did have a lookt at it: https://github.com/spring-projects/spring-boot/issues/15057 Cheerio Johannes ```` 2018-11-02 11:43:33.016 ERROR 17152 --- [nio-8080-exec-2] o.a.catalina.connector.CoyoteAdapter : Exception while processing an asynchronous request java.lang.IllegalStateException: Calling [asyncError()] is not valid for a request with Async state [MUST_DISPATCH] at org.apache.coyote.AsyncStateMachine.asyncError(AsyncStateMachine.java:440) ~[tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.coyote.AbstractProcessor.action(AbstractProcessor.java:494) [tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.coyote.Request.action(Request.java:430) ~[tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.catalina.core.AsyncContextImpl.setErrorState(AsyncContextImpl.java:382) ~[tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.catalina.connector.CoyoteAdapter.asyncDispatch(CoyoteAdapter.java:239) ~[tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.coyote.AbstractProcessor.dispatch(AbstractProcessor.java:241) [tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:53) [tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:770) [tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1415) [tomcat-embed-core-9.0.12.jar:9.0.12] at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) [tomcat-embed-core-9.0.12.jar:9.0.12] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [na:1.8.0_181] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [na:1.8.0_181] at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) [tomcat-embed-core-9.0.12.jar:9.0.12] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_181] ``` --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
