Hi Alan, We recently did a stress test for the home server proxy. However, we found these two kinds of errors that block the server: Wed Aug 20 06:58:04 2025 : Error: Unresponsive child for request 396685, in component authorize module cache Wed Aug 20 06:58:04 2025 : Error: Unresponsive child for request 396689, in component <core> module I know it could be slow SQL queries causing these errors. But I wonder if the slow SQL queries cause the cache module to be unresponsive? Because the errors of the cache module are more than the core module. And I can't see the SQL module being unresponsive. So, I'm unsure where to find the root cause. The SQL server is working fine. We are conducting a stress test with 150 reqs/sec, but I'm unsure if a deadlock issue arises due to setting the max_requests to 50000 and utilizing the rlm_cache_tree driver for the local cache. Please advise how to find the root cause, and I can provide more details if needed. Thank you. Regards, James
