it's because the jvm runs out of address space randomly (due to ASLR the
biggest address space hole size changes randomly, so sometimes this failing
allocation does succeed). now i don't quite see why the address space is
consumed so much based on the strace but i did note that you should be using
PAGEEXEC since your CPU is capable of NX support (you'll also have to enable
PAE in .config).
