Okay, on a big AMD-multicore-laptop the limit in Java seems to be 1GB of memory-mapped files. Ulimit was "unlimited" and --XX:MaxDirectMemorySize was set to 32GB -Xmx was a few GB. I am using the current Java6 -patchlevel 10 from Sun. Strange thing is: Setting MaxDirectMemorySize to 3GB you can't start because some Swing-Code in font-loading can't memory-map the few kilobytes it needs. If I set no limit, it works but failes once the file-size goes over 1GB. I'd like to try this on a 64bit-Linux on that box but don't know how to do that yet. Any help on turning a debian 32bit into a 64-bit or running a 64bit-VM in a 32bit-Linux?
