I have been following the thread here on current@ about problems occuring when running out of memory, so I wrote a C++ program that simply mallocs about 144M of memory. My system has 256MB+491MB(swap). I can run the system out of memory just fine by running multiple copies of the program, and the kernel does kill one if I run too many, however shortly after, when I go to killall the programs the system hangs, (although pings, etc manage to survive for a few mintues longer) and I have no choice but to press the reset button. While it is hung, I _can_ press ^T and it shows the load, which increases by 1 about every 45 seconds: load: 11.58 cmd: killall 20125 [running] 0.00u 0.00s 11% 292k load: 12.27 cmd: killall 20125 [running] 0.00u 0.00s 12% 292k Also, the console is just as unusable as any other terminal. I'm not sure what is going on, but this is reproducible, and I can post more info upon request. -Craig
