    SubjectRe: 2.2/2.4/2.6 VMs: do malloc() ever return NULL?
    On Tue, 25 Nov 2003, Ihar 'Philips' Filipau wrote:

    As documented, malloc() will never fail as long as there
    is still address space (not memory) available. This is
    the required nature of the over-commit strategy. This is
    necessary because many programs never even touch all the
    memory they allocate.

    You can turn OFF over-commit by doing:

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

    However, you will probably find that many programs fail
    or seg-fault when normally they wouldn't. So, if you don't
    mind restarting sendmail occasionally, then turn off over-commit.
