If I add some debug logging are you able to build Tomcat > from source and run your test to collect some more information? Mark, HI I am evaluating Tomcat websockets implementation. For this, I use a client side websockets library that creates connection after connection. After a while (<10000 connections) the error is thrown and Tomcat 8 server hangs for a while. I attached HTTP NIO connector configuration used: <Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="20000" keepAliveTimeout="-1" redirectPort="8443" acceptCount="20000" acceptorThreadCount="8" minSpareThreads="100" maxThreads="10000" maxConnections="-1" URIEncoding="UTF-8" maxKeepAliveRequests="-1" /> Regards, Cristian -- 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
