Server process terminated unexpectedly with exit code

Error message

Server process terminated unexpectedly with exit code: {exit_code}

What it means

Error "Server process terminated unexpectedly with exit code: {exit_code}" thrown in oobabooga/textgen.

Solutions

1. Inspect the server log for the crash cause matching the reported exit code.
2. Verify the model file path, loader flags, and available VRAM/RAM, then restart the server.

When it happens

Trigger: Raised when the llama.cpp server subprocess exits unexpectedly during model load or generation. Triggers on crashes such as out-of-memory, incompatible GGUF/architecture, bad server flags, or missing GPU drivers; the exit code in the message identifies the failure.

Common situations: See trigger scenarios.
