Data upload using data manager

Hi We are running a package in DM that downloads the file to an application folder(Server folder: DATAMANAGER\DATAFILES\) When we need to upload this same file back to application folder it is issuing below memory error: Failed to allocate a managed memory buffer of 33554432 bytes. The amount of available memory may be low. Exception of type 'System.OutOfMemoryException' was thrown. Does anyone has any work around to overcome this error so that I can run process chain /CPMB/IMPORT? Or Is there any process chain that can load the data from any folder on the server and load the data to cube similar to IMPORT process chain? Thanks!
