I think the pragmatic and realistic approach would be to accept that many admins are not perfect, far from it. Also, this bug involves many aspects and it's possible to argue what exactly is the bug. Even if we don't change any default values, we can still change the kernel so that it survives a fork bomb. After all, the Vista kernel does survive a fork bomb although the system as a whole gets unusable. ### On Ubuntu I currently see: 1. Launch fork bomb 2. System gets to a complete freeze (I can't move mouse and not a single pixel is updated on the screen). ### On Vista I currently see: 1. Launch fork bomb 2. System gets very slow to the point where the system is unusable (but I can always mouse around the mouse freely with no sluggishness and the screen updates continue to make progress even though it takes 1-3 seconds between each update). I can still open and close the start menu if I got the patience to wait >45 seconds for it each time. I don't think that setting a max process count by default is a good/viable solution. But the kernel could still be changed so that it doesn't hose itself completely. Martin -
