While troubleshooting repeated crashes of a third-party indexing service on a Windows Server 2022 file server, you find this entry in the Application log:
No abnormal rise in CPU or memory usage is observed before the crash, and other services on the host remain stable. Which underlying condition from the CompTIA Server+ objectives is most likely responsible for the failure?
A buffer overrun in the application's code
A memory leak that gradually exhausts heap space
Improper CPU affinity pinning of the service threads
Clock skew between the server and its domain controller
Windows returns the NTSTATUS value 0xC0000409 (STATUS_STACK_BUFFER_OVERRUN) when it detects that an application has written past the end of a stack-based buffer. The operating system terminates the process to prevent further corruption, so the service stops immediately even though system resources appear normal. A memory leak would show steadily increasing consumption before failure, CPU-affinity issues cause performance problems rather than access-violation crashes, and clock skew affects authentication-not process integrity. Therefore the scenario best matches a buffer-overrun cause.
