This issue has several symptoms:
This issue occurs because smcd is hung while waiting on Java LiveUpdate to complete the following operation:
/usr/java/jre1.7.0_79/bin/java -Djava.security.egd=file:/dev/./urandom -cp /opt/Symantec/LiveUpdate/jlu.jar com.symantec.liveupdate.config.Settings UpdateSetting workdir /opt/Symantec/LiveUpdate/tmp
Java LiveUpdate is hung processing this command because the version of the Java Cryptography Extensions which are installed are incorrect.
This issue occurs because Java LiveUpdate cannot successfully decrypt its configuration file because the version of the Java Cryptography Extensions which Java is using is incorrect. Java LiveUpdate needs to use the Unlimited Java Cryptography Extensions, but the Limited Java Cryptography Extension files are installed.
Download and install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files from here.
