ActiveMQ 6.1 on Arch Linux — all worker threads busy, new requests ETIMEDOUT, timeout after 30s, thread pool 349/349 exhausted, accept queue overflow
Neural Engine Root Cause Analysis
Request timed out — service may be under heavy load, experiencing network issues, or behind a slow upstream.
Remediation Plan
Check server resource utilization (CPU/memory/disk). Investigate network path. Consider scaling if load-related.
