Fix clw-memory-crash: OpenClaw Memory Exhaustion Crash Resolution

The clw-memory-crash error represents one of the most critical failure modes in OpenClaw deployments. When this error manifests, the OpenClaw daemon or its managed containers have encountered an unrecoverable memory state that forces an immediate process termination. Understanding the mechanics behind this crash, implementing proper resource constraints, and establishing monitoring pipelines are essential competencies for any operator managing OpenClaw workloads in production environments.

Fix clw-prompt-oom: OpenClaw Prompt Memory Exhaustion Error

Fri, 07 Aug 2026 05:32:04 +0800

1. Symptoms

The clw-prompt-oom error occurs when the input prompt submitted to OpenClaw exceeds the configured or system-imposed memory allocation for prompt processing. Users encounter this error during normal operations when attempting to process large text inputs, batch operations, or complex multi-line prompts that consume more memory than the application has available or is willing to allocate.

The characteristic shell output when this error manifests typically appears as follows:

[ERROR] clw-prompt-oom: Prompt input exceeds available memory allocation
        Prompt size: 45.2 MB
        Available memory: 32.0 MB
        Suggestion: Reduce prompt size or increase memory limit

In interactive mode, the error presents with additional context about the current session state:

Fix clw-scheduler-crash: Resolving OpenClaw Scheduler Process Termination

Wed, 05 Aug 2026 17:32:04 +0800

The clw-scheduler-crash error represents a critical failure condition in OpenClaw’s distributed task scheduling infrastructure. When the scheduler process terminates unexpectedly, all pending and scheduled tasks become inaccessible, effectively halting workflow automation across the affected environment. This error manifests through distinctive behavioral patterns that system administrators must recognize to implement appropriate remediation measures.

1. Symptoms

The clw-scheduler-crash error presents several observable indicators that help distinguish it from other OpenClaw failures. The most immediate symptom appears in the scheduler logs, where an abrupt termination follows a sequence of warning messages. Log entries preceding the crash typically include memory allocation failures, thread pool exhaustion notifications, or database connection timeouts. The final log entry before termination often contains a stack trace pointing to an unhandled exception in the scheduling loop.

Fix clw-api-oom: OpenClaw API Out of Memory Error

Fri, 31 Jul 2026 15:08:04 +0800

1. Symptoms

The clw-api-oom error manifests when the OpenClaw API service exhausts available memory resources during operation. This memory exhaustion produces several distinct observable symptoms that help identify the root cause and distinguish it from other runtime failures.

Primary Indicators:

API requests begin returning HTTP 503 Service Unavailable responses with extended latency
Process termination events in system logs showing exit code 137 (128 + SIGKILL signal)
Progressive degradation in API response times as memory pressure increases
Container or process restart cycles triggered by the orchestrator’s health checks
Memory usage metrics showing consumption approaching or exceeding configured limits

Fix clw-fs-oom: OpenClaw Filesystem Out of Memory Error

Tue, 16 Jun 2026 03:08:04 +0800

1. Symptoms

The clw-fs-oom error manifests when the OpenClaw workload agent cannot allocate sufficient memory to complete filesystem operations within a running container or pod. This error typically surfaces during intensive I/O operations such as log rotation, volume mounting, or bulk file transfers.

Indicators include:

The OpenClaw agent logging repeated clw-fs-oom messages to stdout or the centralized logging system
Container health checks failing unexpectedly during file-heavy operations
Application pods entering a CrashLoopBackOff state with exit code 137 (SIGKILL due to OOM)
The error appearing in the OpenClaw dashboard under workload events with the specific error code CLW-FS-OOM
Degraded performance when accessing mounted volumes or performing sequential write operations
Memory usage graphs showing a sudden spike followed by a drop to zero (process termination)

Typical shell output:
