Hi, I've tried to compare two XML (each roughly 3MiB in size) using `xmldiff`. But this program have eaten whole RAM and swap and ended up in unresponsive system and then crashed almost everything — X session with all applications — so I've got just tty's. "Nice". Is there any way to prevent such behaviour in future? There is ulimit, but I don't want to limit all of my processes. Nice solution is (IMO) would be to allow every process to reach some limit after which application would be stopped (not killed), some notification sent (if possible) and user (me) could make some decision what to do with it — kill, allow once, add to white list. If program is white-listed allow it to do anything until ulimit/OOM-killer behaviour. Is there any way to do this? I'm not expecting absolutely ready solution, but at least some direction how I can achieve this. The only solution I'm aware of and could do — make some daemon that periodically checks process memory usage and sends SIGSTOP if some of them uses too much, but I'd prefer not use this approach — there is no perfect time period — high CPU usage vs too late to do anything. -- Kind regards, Mykola Krachkovsky -- Найкращі побажання, Микола Крачковський
