Netbeans – Git error on commit

When commit git display error:

java.lang.OutOfMemoryError: Java heap space

The fix was to use below command to change heap size to 6GB:

export JAVA_OPTS="-Xms6144m -Xmx6144m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"

JAVA_OPTS is the standard environment variable that some servers and other java apps append to the call that executes the java command.

For example in tomcat if you define JAVA_OPTS='-Xmx1024m', the startup script will execute java org.apache.tomcat.Servert -Xmx1024m
