German,

Your create-thread udf is going to cause terrible
problems. Don't do it. In superserver, you'll cause
the server to attempt to fork itself - a very very
bad idea - and one that will certainly trash the lock
table, followed almost immediately by trashing all
open databases. In Classic, you'll probably just
block access to the lock table, causing the system
to stop abruptly.

What are you trying to achieve? You can't do it
this way, but possibly you can do it some other way.


Regards,


Ann
