Hi all,
I have a threaded program, which migrates contetn from one repository to another. The program works fine, when I test for small number of documents, say arround 10 or 20. But when I increase the number of documents, then I get java.lang.OutOfMemoryError. I can't seem to figure out how to fix this.
I presume it is the JVM which runs out of memory. Can someone please shed some lights arround this. Now, I am not sure if it's my code, or its JVM setting.
Please advise...
Thanks,

1) Give the program more memory with -Xmx: http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html#options2) Use less memory. That may involved using a smaller thread pool or limiting buffer sizes for file operations, etc.

Two reasons come to mind:
- A rogue implementation which manifests itself as the number of documents to be transferred increases. Profile the application thoroughly looking for memory leaks and unintentional object retention.
- The default heap size doesn't suit well for your current processing needs. Tune your JVM by setting an appropriate heap size and garbage collection strategy to suit your needs.
