Increase the memory setting Xmx in the ARGV line.  Try 4GB first and only increase if the issue continues. For example:

ARGV;$SPECROOT/bin/JavaApps/bin/ncmservice<CSEXE> -Xms256M -Xmx8192M -XX:+HeapDumpOnOutOfMemoryError -Dvbroker.agent.enableLocator=false -Dvbroker.orb.admDir=$SPECROOT/bin/VBNS -Dborland.enterprise.licenseDir=%BES_LIC_DIR% -Dborland.enterprise.licenseDefaultDir=%BES_LIC_DIR% -Djava.endorsed.dirs=$SPECROOT/lib/endorsed -DSPECROOT=%SPECROOT% com.aprisma.spectrum.scmd.ScmService;
