I get this heap space error. mynode has 5 million records

Error:
com.orientechnologies.orient.enterprise.channel.binary.OResponseProcessingException:
Exception during response processing.
Error: java.lang.OutOfMemoryError: Java heap space

I have tuned the server this way
 -d64 -Xms512m -Xmx2g -Dfile.mmap.maxMemory=3.2gb

Any pointers on tuning plz

Regards
