Is everything alright with llama.cpp recently?

My Gemma4 31b seems to be breaking down in 'lalala' or just looping indefinitely for the past 3-4 days. Never happened before

There was no 'lalala' in the whole scenario, I have no idea where it came from. Nor was there any skipping, humming or perfection. There were shivers down the spine of course, but it is still weird.
