To resolve this issue:

Edit the <kafka_home>/bin-kafka-run-class.sh file.
Locate the following line:

KAFKA_GC_LOG_OPTS="-Xloggc:$LOG_DIR/$GC_LOG_FILE_NAME -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps"

To enable verbose logging, change it to:

KAFKA_GC_LOG_OPTS="-Xverbosegclog:$LOG_DIR/$GC_LOG_FILE_NAME -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps"

Save the file.</code>
