There should be no way for a Java program to prevent the JVM from
going down on a kill signal, let alone a kill -9. The latter
usually indicates the JVM hangs somewhere in kernel code, some
suspects:
- a bug in a device driver
- a hardware defect
- corruption of a kernel related binary or a device driver
There are of course half a zillion other possibilities, including
problems with thread deadlocks mentioned elsewhere.
Your options: Run a hard disc health check. Make sure the box is
pingable on all interfaces after it hangs. Try to run the code on
another machine, preferably on another JVM and/or OS, and check
whether the problem pops up there too.
