Problem Loading SSAS Dimension With SSIS

I am trying to perform an incremental (ProcessAdd) load on a dimension using SSIS and the Dimension Processing data flow component. Whenever I try the load it fails with the following error:

The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC02020C4

Apparently this translates to the error DTS_E_ADDROWTOBUFFERFAILED.

This incremental load is trying to add several hundred thousand rows and it appears to get to around 10K or so and then fail. I can't seem to find any KB articles related to this problem. Does anyone have a clue what may be happening here?

I do have an incremental load of the same type that is working but I am continually getting the following warning when the load is running:

"The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 6 buffers were considered and 6 were locked. Either not enough memory is available to the pipeline because not enough is installed, other processes are using it, or too many buffers are locked."


My server has 8GB of memory and is running WS 2003 x64 and SSAS 2005 x64
