You're running on a Linux machine with memory overcommit enabled.
Turn that off, or nothing will ever work very reliably --- the OOM
killer is entirely capable of zapping innocent processes that have
nothing to do with the one eating too much memory; and even when it
kills the right process, "kill -9" is not IMHO an acceptable way for
the system to tell a process it can't have any more memory.  See
