I found on systems I managed that turning off memory overcommit helped, but your mileage may vary.

Normally malloc() always succeeds on Linux, whether there's enough memory to handle the request or not. Turning off overcommit causes it to return NULL if there isn't enough memory, as God intended. ;) Most processes don't trap this very well (because malloc() always succeeds, right?) and will crash, but the system will stay up.
