Explanation:

Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads. Reference:
