This only occurs once in a while, but its still annoying. I'm running a 2.4.27 kernel, and every so often the system will freeze for a short time. Sometimes it will snap out of it, but other times, it will stay frozen. When it is frozen, the CPU usage goes to 100% and stays there until it unfreezes. I've checked the messages, and the worst I've come up with is
Sep 9 17:10:38 Brain kernel: spurious 8259A interrupt: IRQ7.
but that is an hour before it actually froze. Just recently i got this. the computer froze and X died, but i couldn't switch to any of the terminals. I had to ssh in and restart it to get any control over the computer.
Sep 9 18:28:13 Brain kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
Sep 9 18:28:15 Brain last message repeated 2 times
Sep 9 18:28:15 Brain kernel: VM: killing process X
Right above that was a whole bunch of programs being killed by VM. I don't think that i was doing anything memory intensive, just using the computer normally. I have run memtest for a while, no errors on 256 MB of ram. my swap partition is 512 MB.
Actually, what does "__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)" mean? I've gathered that it means that the computer is running out of memory, but I'm not sure.
