Humberto, You have ~10GB of physical (real) RAM free on the system, so you shouldn't be so eager to use swap (fake) memory yet. What is the size of Tomcat's JVM heap? If it's an Ubuntu server, you can see the JVM_OPTS variable in /etc/default/tomcat7. For example, ours is:
JAVA_OPTS="-Djava.awt.headless=true -Xms5120m -Xmx5120m -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8" This allows Tomcat to use 5120MB of memory on our system. If you're having memory issues with Solr, you should try to increase this JVM allocation—I recommend increasing by 512 or 1024MB intervals and testing.
