There's a great post on Pager Duty today, http://www.pagerduty.com/blog/the-discovery-of-apache-zookeepers-poison-packet/ some good comments on hackernews too https://news.ycombinator.com/item?id=9509698
If I understand correctly bug1 is already fixed: https://issues.apache.org/jira/browse/ZOOKEEPER-2146 should be released in 3.4.7+ However bug2 https://issues.apache.org/jira/browse/ZOOKEEPER-602 is just in 3.5 and not 3.4.x. Note my push back in the comments on 602 re risk vs reward. Evan makes a good case for including it. :-) We should also recommend that folks run with -XX:-HeapDumpOnOutOfMemoryError I would think. That should have caused the jvm to restart when bug1 was hit. Thoughts? Hongchao can you confirm that 2146 fixes bug 1? Patrick
