Mathematica 4.0
I'm grinding away, brute force searching for rare candidates

   Timing[Select[Range[28500,29500], f ]

bumping the range up by 1000 each iteration, taking tens of
thousands of seconds each time to complete.  It appears to
have worked again and again, each time returning something like

   { 41367.2, {}}

But last night it returned

   { Null Second, {}}

I've searched all the documentation and can't find this.

Anyone have an idea whether the run failed?  Or whether
some other error popped up?
