Bug ID: 63379 Summary: Tomcat socket listening timeouts Product: Tomcat 9 Version: 9.0.16 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P2 Component: Catalina Assignee: dev@tomcat.apache.org Reporter: vojt...@knyt.tl Target Milestone: ----- We just updated from JDK8 to JDK11 and our Tomcat started reporting this warning (we use Docker image tomcat:9-jre11-slim): 2019-04-17 10:17:35.060 WARNING [:tomcat] org.apache.catalina.core.StandardServer The socket listening for the shutdown command experienced an unexpected timeout [256] milliseconds after the call to accept(). Is this an instance of bug 56684? java.net.SocketTimeoutException: Accept timed out at java.base/java.net.PlainSocketImpl.socketAccept(Native Method) at java.base/java.net.AbstractPlainSocketImpl.accept(AbstractPlainSocketImpl.java:458) at java.base/java.net.ServerSocket.implAccept(ServerSocket.java:551) at java.base/java.net.ServerSocket.accept(ServerSocket.java:519) at org.apache.catalina.core.StandardServer.await(StandardServer.java:607) at org.apache.catalina.startup.Catalina.await(Catalina.java:722) at org.apache.catalina.startup.Catalina.start(Catalina.java:668) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:350) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:492) The bug #56684 mentioned in the warning refers to this: https://bz.apache.org/bugzilla/show_bug.cgi?id=56684 - which is probably fixed and not very relevant. We get hundreds of these exceptions in our logs and we have disabled it with setting -1 to the shutdown port as a temporary solution. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
