That should work -- there must be something else going on with your
install.

It appears that you have run out of available kernel memory.
This sometimes occurs because you have too little memory, but in later
2.2.* kernel the usual cause is badly tuned kernel memory allocation.
You can't fix the algorithm, but you can minimize the impact by setting
the values in /proc/sys/vm/freepages to a larger number
