Reason:

The default java memory arguments  provided in bsu.sh file are not sufficient

Solution:

Increase the Java memory values in bsu.sh file (under $MW_HOME/utils/bsu) by adjusting the value MEM_ARGS values.

By default the values will be

MEM_ARGS="-Xms256m -Xmx512m"

I increased it to 1024-1024 as follows

"-Xms1024m -Xmx1024m"

Save the bsu.sh file and re-execute the patching command.
