I'd recommend testing with to 8.5.12 and 1.2.12. If you still see the issue, any information you can provide on reproducing it would be helpful. Failing that, you could try narrowing down whether the problem depends on the use of any of: - HTTP/2 - Servlet async - send file - web socket etc. In short, the more information you can provide the better the chances of us being able to help you. You should probably look at using -Dorg.apache.catalina.connector.RECYCLE_FACADES=true Mark > > The exception show in catalina.log : > > 18-Mar-2017 03:36:01.135 WARNING [http-apr-2181-Poller] >> org.apache.tomcat.util.net.AprEndpoint$Poller.run Unexpected poller error >> java.lang.NullPointerException at >> org.apache.tomcat.util.net.AprEndpoint$AprSocketWrapper.access$400(AprEndpoint.java:2243) >> at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1654) >> at java.lang.Thread.run(Thread.java:745) >> > > I searched find similar with issue 54513 > <https://bz.apache.org/bugzilla/show_bug.cgi?id=54513>, but looks an > old one and fixed. > > Anyone hit this issue, any information can I look up? > > Thanks, > > Linbo > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
