Cause

The issue happens if the default heap size used by the Smart Update java process is insufficient while launching the Smart Update GUI or applying the patches.

Solution

To resolve this issue, increase the heap size for bsu inside the bsu.cmd or bsu.sh script inside WL_HOME/utils/bsu directory. Add Xms and Xmx arguments for increasing the heap size.
For example, set Xms and Xmx values to 512m for the BSU process inside bsu.sh script inside WL_HOME/utils/bsu directory:

#!/bin/sh
JAVA_HOME="C:/BEA/WLS92.3/jrockit_150_12"
"$JAVA_HOME/bin/java" -Xms512m -Xmx512m -jar patch-client.jar $*
