This issue can occur due to various reasons, such as excessive recursion or an infinite loop in the code. The error message indicates that the listener encountered a `java.lang.StackOverflowError` while processing. This is often related to the system running out of stack space due to deep or infinite recursion.
The StackOverflowError typically occurs due to excessive recursion or an infinite loop in the code. Here are some steps to troubleshoot and resolve the issue: 1. Review the Code: Check the code associated with the email listener for any recursive calls or loops that might be causing the stack overflow. 2. Increase Stack Size: If the recursion or loop is necessary, consider increasing the stack size of the JVM. This can be done by setting the -Xss parameter in the JVM arguments. 3. Debugging: Enable debugging for the email listener to get more detailed logs. This can help identify the exact point where the error occurs. 4. Optimize Logic: If possible, optimize the logic to reduce the depth of recursion or the number of iterations in loops.

Please log a support INCIDENT via the msp and provide the INC id here so we can help track it.

@MarijeSchillern Thanks Marije, Let me debug end to end code and get back. Thanks again!
