Re: Systemfunc error

Marco,

Dave and I discussed this, and need more information.

    - How many times is this procedure being called? Is it just
      a few times, or 100s of times, or more than that?

    - Are there any other error or warning messages appearing
      before the fatal message?

    - Is the script you're running memory intensive in any way?
      That is, are you doing something like opening and closing a lot
      of files, creating large variables, running big do loops, or
      doing a lot of variable reordering?

    - You said the script doesn't fail consistently, correct?
      Is it possible that the problem is with the load on your machine?
      That is, are there lots of other users running jobs on the
      same system?
