Just thought of something.  Please set the
vm.overcommit_memory syscall to 2  (it is available in /proc/sys, I think.
But the right way is to use /etc/sysctl.conf and sysctl).

Make *really* sure you have enough swap when you do that. You will *really*
need it.

Some look on /proc/meminfo (especially on CommitLimit and Committed_AS)
might shed some light if that is the problem.
