Multi-core Related Test Cases Hanging in ACS Test

[bitboom]

The ACS Test hangs depending on the amount of logging.
This issue occurs only in the multi-core test case (cmd_multithread_realm_mp).

Steps to Reproduce:

1. Use the current main code (commit).
2. Insert the below code snippet.
3. Run the test, and the system hangs.
