I'm using AIX 3.2 and one of the users is running a fortran executable. After about 30 minutes he gets a message saying that "CPU Time Limit Exceeded"..

Does anyone knows what this is and how can I resolve it,

 Check their 'ulimit' options.  Use 'man ulimit' for more information.
  Maybe ulimit has been used in their login scripts, or perhaps system login scripts, to control the resources a person can use.
  You should be able to type

  ulimit -t unlimited

to prevent this CPU time restriction.

Actually, what I used was the CPU Time Limit under the smit utility, and increased the value. This worked fine. I think ulimit changes this same value.
