Hello! Sorry for the late answer: I've missed the question somehow. Have you tried adding -Xmx30G option to java? By default it use only 4Gb. The full command will look like:

java -Xmx30G -jar VirGenA.jar map -c config_copy.xml

If this doesn't help, please tell me more details: the genome length, the read length, the number of reads.
