    Description

      Jenkin's encountered a failure in TestTolerantUpdateProcessorCloud over the weekend....

      http://jenkins.thetaphi.de/job/Lucene-Solr-6.x-Solaris/32/consoleText
      Checking out Revision c46d7686643e7503304cb35dfe546bce9c6684e7 (refs/remotes/origin/branch_6x)
      Using Java: 64bit/jdk1.8.0 -XX:+UseCompressedOops -XX:+UseG1GC
      

      The failure happened during the static setup of the test, when a MiniSolrCloudCluster & several clients are initialized – before any code related to TolerantUpdateProcessor is ever used.

      I can't reproduce this, or really make sense of what i'm (not) seeing here in the logs, so i'm filing this jira with my analysis in the hopes that someone else can help make sense of it.
