Long responses can corrupt the model until unloaded

### What is the issue? In a relatively simple prompt, one of the Phi models went off track and ranted for several thousand words. After, all future responses produced (mostly) garbage output, even in separate API calls or interactive sessions with cleared session context. This persisted until the model was completely unloaded and reloaded. It feels like something may have overflowed a buffer used for the context window or response and corrupted the model weights. Within the garbage output, the model appeared to have brief periods of "lucidity" where it demonstrated knowledge of prompts from completely separate sessions. In the most recent case, I was using `phi3.5:3.8b-mini-instruct-q4_K_M` but have seen the same sort of behavior in other Phi releases. I'll try to find a prompt that can replicate this, though it's obviously stochastic given the nature of LLMs. ### OS Linux ### GPU Nvidia ### CPU Intel ### Ollama version 0.3.12
