| |
I have an Xserve running 2.6.9-rc3 and patched to run the ppc kernel rather than the ppc64 kernel. It's configured with 2GB of memory, no swap.
If I run one instance of the following program, it allocates all but about 3MB of memory, and the memory hog spins with 100% of the cpu.
If I run two instances of the program, the machine locks up, doesn't respond to pings, and is basically dead to the world.
Shouldn't the oom-killer be kicking in?
