Additional Information

This issue seems to result from an insufficient heap size allocated to the Java Virtual Machine (JVM). The Java heap space is the memory area utilized by the JVM to store objects instantiated by applications; it is the primary memory space utilized by the Java application. If the heap memory is too small for a given application, the out of memory error is returned in logs. Increasing the maximum heap size of the Tomcat server is required to prevent this error.

Workaround

Increase the Java Maximum memory pool used by Tomcat. Depending on how high the value is set, this issue may reoccur. Refer to the image below.
