You have allocated 4GB to Java's heap and the rest of the 4GB RAM (i.e. zero) you have allocated to data storage.
Try 1) running on a larger machine. Having >8G memory will make these worries go away. 2) decreasing memory requirements. Here is one possibility that may or may not work out well: DRILL_MAX_DIRECT_MEMORY="2G" DRILL_MAX_HEAP="1G" export DRILL_JAVA_OPTS="-Xms100M -Xmx$DRILL_MAX_HEAP -XX:MaxDirectMemorySize=$DRILL_MAX_DIRECT_MEMORY -XX:MaxPermSize= -X200M X:ReservedCodeCacheSize=500M -ea" Note that decreasing these sizes puts you into untested territory.
