How to deal with "Too many load/unload tasks running: try again later

Question

I have tried the fastload and it worked all right the first time . When I ran it the second time i got Too many load/unload tasks running: try again later . Then I closed the connection and tried again and it worked .

Then i tried to replicate everything again to check whether closing connection deals with Too many load/unload tasks running: try again later and was not able to fastload .

Does closing connection guarantee no problem with Too many load/unload tasks running: try again later ? If no , then what does ? Is there any command that deletes ALL miltithread loads associated with the Connection so that one can proceed with fastload without this error ?

Depending on the database version Teradata constrains the number of concurrent load utilities that are permitted to run. In releases prior to Teradata 13 or 13.10 this limit was managed in the DBS Controls. Starting with Teradata 13 or 13.10 utilities limits were managed by Workload Management ruleset via Viewpoint.

It is not uncommon for load utilities to be further constrained during the time period which is reserved for end users or the business.Something else that may come into play is whether you are running on an Appliance or an Enterprise class system which you haven't indicated.

If you are not the DBA of the environment I would suggest consulting with the DBA responsible for the environment.
