Developer details 6 critical LLM gateway failures and fixes

A developer detailed the challenges encountered when running 33 different LLM models through a single endpoint over a month. Key issues included long connection timeouts that didn't account for stalled connections, a single rate-limiting error freezing all models from a provider, retry stampedes caused by synchronized failures, a byte-order mark corrupting JSON configurations, silent connection failures, and data loss due to a lack of checkpoints. The developer implemented solutions such as inter-chunk idle deadlines, scoped cooldowns, jittered exponential backoff, JSON parsing adjustments, detailed connection status monitoring, and an append-only checkpoint journal to create a more robust LLM gateway.
