Hello everyone,
While I was cleaning my home directory, I saw this program that I compiled.
After that, I launched it and... My X became frozen and then crashed ( I
executed the program in an Xterm). I think it's because it used all the memory
available...
I don't want to try but what could happen if I'd have run it from a console
? Whould the system crash ?
I think there is a way (or more than one) to be sure a user doesn't crash
the system by using all the memory available.
I've heard a bit about the /etc/limits file but it seems that it's a per
login configuration, which has a lot of disadvantages. I'd like to know if
there is a way to impose GLOBAL/per user limits. If a such {program ;
configuration file } exist, I'd like to know why debian shouldn't be
configured to impose quotas by default. I think it's very disapointing to
let every user crash the system by default :-((
Have you a better idea to avoid this kind of program to crash the system ?
Thank you very much for giving me much infos
