Re: Pre-allocation of shared memory ...

OK, new text is:

<para>
Linux has poor default memory overcommit behavior. Rather than
failing if it can not reserve enough memory, it returns success,
but later fails when the memory can't be mapped and terminates
the application with <literal>kill -9</>. To prevent unpredictable
process termination, use:
<programlisting>
sysctl -w vm.overcommit_memory=3
</programlisting>
Note, you will need enough swap space to cover all your memory needs.
</para>
</listitem>
</varlistentry>
