This is just a guess, I have read something here, that could possibly fit.

You transfer here 448 parameters to a function (loop(Assets)), maybe jcl can clarify on whether this is still problematic or not?

I can not test your script, unfortunately I do not have so many assets or data from 1993.

Set Verbose higher, enable DIAG and debug deeper, use stepping for debugging with watch("!blabla"), look into the logfiles...
