Chris,

This is very helpful. It strongly suggests the issue is memory management, not JFreeChart.

I'd put my money on bad hardware. Every single time I've seen a release version of a JVM fail, it's because of bad memory, CPU, motherboard, or the combination thereof.

I recommend trying the same code and configuration on a separate physical machine to see if that might be the problem. Does Mac have anything like memtest86? Can you even run that on x86-based Macs?

My initial presumption was bad memory, but after running a very intensive memory test (provided by Apple), no problems were found. Also, no other process results in a JVM crash. Only when JFreeChart is run does the JVM crash. This is an X-Serve, dual core intel that has 12 gigs of RAM running OS X 10.5.
