Two random thoughts from your last comment

- If you do

echo "2" >/proc/sys/vm/overcommit_memory
echo "80" >/proc/sys/vm/overcommit_ratio

do you instead get out of memory kills (which would imply bad memory
leaks perhaps triggered by glibc ?)

- Does your system pass 'crashme' testing (run as a non root user). If
not then that might give an eventual identification of a crashme run
which takes out the box. We've found kernel bugs, CPU bugs and
combinations of the two before now that way.
