Ok, I have finally inspected the table. 3 triggers where being called, each one executing sp_runwebtask.

Thanks a lot for helping!!! 🙂

I have just dropped them. I believe the triggers had been created just for experimenting. Will dig further on tomorrow and post my findings.

You can find what procs and triggers are calling it with a search such as:

SELECT s.name AS schema_name, o.name AS object_name, o.type_desc
  FROM sys.objects o
...

Yes! 3 bloody triggers where set for that table. Deleted them fixed the problem!! Thanks!
