Please can you give us a recipe for provoking the bug using the sun jvm
(or better, a little program that just does the mmap).

[or are you saying that just running 'jave -version' a bunch of times
causes the issue? ]

When the machine is in the sick state, the output of 'free', 'ps auxw'
an 'cat /proc/slabinfo' may be useful.

Thanks,
Ian
