Jobs wont work if run more than one at a time.

So I recently started moving servers. I have moved a group of jobs all under one folder to my new server. when I try to drop a computer into it it gives me the following error: “Error scheduling jobs through the database management service. Last error was “an error occurred while attempting to execute a DB stored procedure”” I have checked and the Altiris Database service is started. but for somereason it wont allow me to do run more than one job at a time... this is to say that I have been able to run one and only one job at a time successfully.
