Jonathan Ellis created CASSANDRA-4422:
-----------------------------------------

             Summary: Humor 32bit JVMs
                 Key: CASSANDRA-4422
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4422
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.1.0
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 1.1.3


The commitlog rewrite for 1.1 uses mmap, anticipating multithreaded commitlog writes.  However,
the default commitlog settings will quickly exhaust a 32bit address space.
