[infinispan-issues] [JBoss JIRA] Updated: (ISPN-1017) HotRod client test suite hangs eating 100% CPU

[ https://issues.jboss.org/browse/ISPN-1017?page=com.atlassian.jira.plugin.... ] Dan Berindei updated ISPN-1017: ------------------------------- Summary: HotRod client test suite hangs eating 100% CPU (was: Livelock creating lots of cache managers in parallel) Description: The HotRod client test suite sometimes sometimes hangs on my machine and the thread dump shows a lot of stack traces like this:
