Subject [jira] [Created] (JCR-3427) JCR-3138 may cause resource starvation
Date Mon, 17 Sep 2012 11:52:07 GMT
Marcel Reutegger created JCR-3427:
-------------------------------------

             Summary: JCR-3138 may cause resource starvation
                 Key: JCR-3427
                 URL: https://issues.apache.org/jira/browse/JCR-3427
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: clustering, jackrabbit-core
    Affects Versions: 2.3.7, 2.3.6, 2.3.5, 2.3.4, 2.3.3, 2.3.2
            Reporter: Marcel Reutegger
            Priority: Minor


The new feature introduced with JCR-3138 may cause resource starvation when enabled. Consider
a two node cluster where one of them writes continuously. The second cluster node will start
synchronizing those changes from the journal while it holds a read lock on the journal. This
lock is never released when new records are continuously available. Write operations on second
cluster node will therefore be blocked forever because it cannot get hold of the journal lock.
