Fix clw-memory-oom: OpenClaw Out of Memory Error Resolution

Sat, 13 Jun 2026 17:32:04 +0800

1. Symptoms

The clw-memory-oom error occurs when an OpenClaw-managed workload exhausts its allocated memory resources. This error manifests through several distinct symptoms that help identify the root cause.

Primary Symptoms:

When the memory limit is reached, the OpenClaw runtime generates a specific error event:

[ERROR] clw-memory-oom: Container workload-xyz exceeded memory limit [ERROR] Current usage: 2048Mi, Limit: 2048Mi [ERROR] Memory allocation request rejected


**Observable Symptoms:**

- **Container restart loops**: The workload container enters an `OOMKilled` state and restarts repeatedly
- **Application crashes**: The process terminates unexpectedly without graceful shutdown
- **Memory metric spikes**: In monitoring dashboards, memory usage graphs show a sharp vertical line at the limit threshold
- **Health check failures**: Liveness probes fail after the container is killed
- **Pod status changes**: In Kubernetes environments, the pod status shows `OOMKilled` or `CrashLoopBackOff`

**Log Output Examples:**

2. Root Cause

The clw-memory-oom error stems from a fundamental mismatch between memory consumption and memory allocation. Understanding the underlying causes is essential for implementing an effective solution.

1. Symptoms

The clw-scheduler-oom error manifests when the OpenClaw scheduler service exhausts available system memory during workload scheduling operations. This error typically surfaces under high-load conditions where the scheduler must manage numerous concurrent jobs, evaluate complex dependency graphs, or process large volumes of task queue entries.

Primary symptoms include:

The scheduler process terminates abruptly or enters an unresponsive state. When monitoring the scheduler service, you may observe the process exit with code 137 (128 + 9, indicating SIGKILL) or the container being forcibly terminated by the OOM killer.
