Also, this kind of points out that you might not have enough swap
space. On most database servers there's enough hard drive space laying
about to have as large a swap space as you'd like, and I can't count the
number of times a large swap has given me enough to time to catch
runaway processes and keep an ailing server up and running, albeit
hobbling along, rather than having to worry about running out of virtual
memory.
Unless the memory being allocated here just has to be real memory. But
I'm guessing not. Sure, swapping is slow, but at least it will let some
memory hungry processes finish.
