CRM std extractor failing with a java- VM container error

When running 0CRM_COMPLAINTS_I in rsa3 in CRM, we are getting the following error: "Error occurred when processing Java programs VM container". When checking the errror log in SM52 it says 'RFC Server (in-process) stopped, java.lang.OutOfMemoryError:[Ljava.util.HashMap$Entry;, terminate VM'. When i reduce the package size of data extraction to less than 60 records, rsa3 runs fine. We have checked for oss notes but could not find a solution. Can someone tell whats happening here and how to fix it?

Thanks.
