[ https://issues.jboss.org/browse/ISPN-8902?page=com.atlassian.jira.plugin.... ] Radim Vansa commented on ISPN-8902: ----------------------------------- I can't reproduce this with {code:java} package org.infinispan.client.hotrod; import org.infinispan.client.hotrod.configuration.ConfigurationBuilder; import org.infinispan.test.AbstractInfinispanTest; import org.testng.annotations.Test; @Test(testName = "client.hotrod.UnknownHostsTest", groups = "functional") public class UnknownHostsTest extends AbstractInfinispanTest { public static void testFastFailure() { ConfigurationBuilder cfg = new ConfigurationBuilder(); cfg.addServers("127.0.0.1:11222; 127.0.0.2:11222; 127.0.0.2:11222; 127.0.0.3:11222; 127.0.0.4:11222;"); RemoteCacheManager cacheContainer = new RemoteCacheManager(cfg.build()); RemoteCache<String, String> cache = cacheContainer.getCache(); } } {code} and given the thread dump with KQueue this might be specific to Macs. Awaiting trace logs. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
