What is the issue?

I am using ollama for deepseed coder model make fill-in-middel inference, and it was working fine initially. However, after more than 50 consecutive inferences, the model output suddenly became abnormal, producing nonsensical content.

abnormal output like this.

#generategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerategenerate

In these calls, the call parameters remain consistent.

data = {
                "model": "deepseek-coder-v2:latest",              
                "prompt": prompt,
                "raw": True,
                "stream": False,
                "keep_alive": -1,
                "seed": 40,
                "options": {
                    "num_predict": num_p,
                    "top_k": 1,
                    "top_p": 0.0,
                    "temperature": 0.0,
                    "repeat_penalty": 1.1,
                }
