{"answer":"Recommended action: Create the Langfuse client lazily inside each worker (post-fork hooks / worker_process_init), avoid --preload for tracing code, and flush() before process exit.\n\nOption: Initialize per worker [evidence: documented_workaround]\nApplies when: Pre-fork servers\nSteps:\n1. Move Langfuse()/get_client() into a post-fork hook\n2. call flush() on shutdown\nExpected: Each worker owns live threads/pools","applicability":{"state":"unknown"},"limitations":{"state":"unknown"},"risk_notes":null,"success_criteria":null,"sources":[],"id":"71ee63a2-1e8b-47fe-8d59-2ccc677cbb2a","kind":"solution","title":"Proposed fix: [Langfuse Python SDK] Forked workers (gunicorn/Celery prefork): \"Failed to recreate HTTP clients after fork ...
