What happens after executing a trigger that creates a child Case for each new parent Case created?

The scenario involves creating child Cases for every new parent Case when a trigger is executed. This operation can potentially lead to an infinite loop if not correctly designed. When you create a new child Case within the trigger for each parent Case, the creation of these child records can cause the same trigger to fire again because the child Cases may also trigger the same logic upon being created.

In more detail, if the trigger is designed to run on the creation of parent Cases, and every time a parent Case is created, it subsequently generates child Cases that also invoke the same trigger (if it is set to execute on child Cases), it can lead to the original parent Cases triggering the process again. Without proper recursion control or adequate termination criteria to stop this cycle, the trigger will keep invoking itself indefinitely until it exceeds allowable resource limits in Salesforce, causing the operation to fail.

This is a common issue encountered with triggers that need careful management to avoid such infinite loops. If safeguards, such as static variables or trigger context checks, are put in place, this behavior can be mitigated, but without those, the risk of entering a loop exists.
