The security department was responsible for porting/implementing the BSD-style quota mechanisms. For reasons not worth going into, that functionality was not put in AIX v3.1, but is/was scheduled to appear in a "future" release, whatever that means (I don't speak for IBM, that's one thing it means ;-). You will =never= get EQUOTA or whatever returned from a system call because you ran out of file system space or any other resource. I've never tried to run out of CPU time, but I seem to recall that the CPU time limit is also not enforced. As others have pointed out, there are a number of attributes in /etc/security/limits which are documented as not being used. Yup, they aren't used. -- John F.
