"When I get a chance, maybe..."??? Greg gave you the answer. A default JVM instance heap space is limited to 64 Megabytes. If the file you're loading, plus the memory consumed by your application, goes over that memory limit the JVM will report "out of memory" and begin exhibiting unpredictable behavior. It make no difference how much physical RAM your machine might contain. The JVM will NOT use more heap space that the maximum defined by the -xmx argument (-xmx64m being the default when not specified). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
