Philip Thompson created CASSANDRA-7353:
------------------------------------------
Summary: Java heap being set too large on Windows with 32-bit JVM
Key: CASSANDRA-7353
URL: https://issues.apache.org/jira/browse/CASSANDRA-7353
Project: Cassandra
Issue Type: Bug
Environment: Windows Server 2008, 8G RAM, 32-bit JVM
Reporter: Philip Thompson
Assignee: Joshua McKenzie
Priority: Minor
On windows, the JVM settings for max heap size and new gen heap size are set
based on the total system memory. When the system has 8G of RAM, the max heap
size is set to 2048M. However, according to http://goo.gl/1ElbLm, the
recommended max heap for a 32 bit JVM on Windows is 1.8G.
When cassandra is started on Windows under these conditions, the following
error is seen:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
