Stop OpenClaw from Spawning Multiple Local LLM Instances on LM Studio
OpenClaw can inadvertently spin up multiple instances of your local LLM when using LM Studio, leading to resource exhaustion and timeouts—especially on memory-constrained machines like the 16GB Mac Mini M1. One user on r/openclaw details this exact issue and asks for a fix.
The Problem
- Default model: Qwen 3.5 9b running in LM Studio.
- After sending a prompt, OpenClaw starts an additional instance of the same model.
- While the first prompt is still processing, another instance gets launched.
- Eventually the user hits a timeout and a guardrail warning saying they're out of resources.
Why It Happens
OpenClaw appears to treat each incoming request as a separate task, loading the model again instead of reusing the existing session. This is common when local model servers are not configured for job queuing or concurrent request handling.
What the User Wants
The user explicitly says: "I only have a 16GB Mac Mini M1, so I'd rather just have 1 instance running and queue more requests if need be." They're asking for a way to prevent OpenClaw from creating new model instances and instead queue additional requests.
Possible Directions (From General Knowledge)
The source post doesn't include a confirmed solution, but common approaches include:
- Check LM Studio's server settings for max concurrent requests or model loading behavior.
- Set OpenClaw's concurrency limit to
1via configuration (concurrency: 1inopenclaw.configor environment variable). - Ensure LM Studio is set to keep model loaded and not unload on idle.
- Look for any request queueing options in OpenClaw's settings.
As of the source date, the user is awaiting community input. If you've hit this, check your OpenClaw config for concurrency-related keys and LM Studio's server options.
