Error while refreshing salesforce metadata in BW5.11 Designer tool

TIBCO BW Support Team,

In BW-5.11, While trying to refresh salesforce metadata file, it takes long time and sometimes it errors out due to large data coming from salesforce server for metadata refresh and designer keeps that in memory until all the data gets from server. Usually its a large file and in-spite of my designer Java Heap size set to 2GB, it still errors out. Is there anyway to limit the refresh to a specific object of interest from salesforce server instead of pulling everything in one go and eats out memory while accumulating results Please suggest any alternative approach for metadata refresh so that it doesnt consume lot of your computer memory for refresh.

Thanks
