What is the issue?

Hi,

currently I run v0.13.2 and I have sometimes loops in thinking process with gpt-oss:20b (https://ollama.com/library/gpt-oss:20b).

I'm using Open WebUI v0.6.41.

Is there a way to see why this happens? Cause sometimes it's not working, when I click stop in Open WebUI.

Or it's possible to stop this.

In this case the whole GPU (RTX A6000 48GB) is used and blocked.

Regards,
somera

I go back to ollama 0.13.1.But the loop is there.

Weeks ago I set this: Environment="OLLAMA_KV_CACHE_TYPE=q8_0". Now I deactivated this parameter and I use the default value.

But with some Java code files which should be analyzed I get loops in thinking step.

The problem is: the wrong model for this use-case. ;)
