To: "user@zookeeper.apache.org" Content-Type: text/plain; charset=UTF-8 X-Virus-Checked: Checked by ClamAV on apache.org I am looking into this issue: https://issues.apache.org/jira/browse/ZOOKEEPER-1934 We believe that a server gets into a permanently hosed state and we're trying to figure out how to debug it the next time we see it. Has anyone ever run with -Xdump? Should I expect problems? Has anyone had success debugging server problems from a jvm core dump? Thanks! Jared
