Looks like some environmental issues in jenkins slaves are causing some of our flakey test issues: https://issues.apache.org/jira/browse/INFRA-11811
However I notice a number of failures are not environmental, often I see issues related to https://builds.apache.org/job/ZooKeeper_branch35_jdk8/72/ [exec] /home/jenkins/jenkins-slave/workspace/ZooKeeper_branch35_jdk8/branch-3.5/src/c/tests/TestReconfig.cc:183: Assertion: equality assertion failed [Expected: 1, Actual : 0] Can someone take a look at this? There's a jira pending for it: https://issues.apache.org/jira/browse/ZOOKEEPER-2152 Patrick
