I am pretty sure that I am going to have to call MS Support on this issue, so I thought I would bounce it off of ya'll first and get my thoughts in order. Env - Win2k3 SP2 EE, 2 node, 2 instance cluster, MSSQL 2000 EE SP4 Problem. On one instance we have about 180 jobs that run nightly to populate a data warehouse type solution. These jobs basically truncate the tables then pull in data out of CSV files to repopulate the data. Of these 180 jobs, there are approximately 15 that error almost every night with the following error. Error = -2147467259 (80004005) Error string: Error creating file mapping view: Insufficient system resources exist to complete the requested service. Error source: Microsoft Data Transformation Services Flat File Rowset Provider However, they don't ALWAYS error only about 5 days out of 7. Also, they are not all "big" tables, some load when running in less than 15 seconds, while some run for 7 minutes. Now for the strange part, at least in my mind... These jobs only error when executed via a job, I can, and do, fire up 4 instances of EM and execute the DTS packages manually in parallel and they run just fine. The problem is that I have to do this sometime in the middle of the night before other dependant jobs start up that will fail if these tables are empty. Anyone have any ideas or need any more information?
