All Errors

The "Eviction Hard Threshold" error occurs when a node reaches critical resource thresholds (memory, disk, or inodes) and the kubelet forcibly evicts pods to free resources. When a hard threshold is breached, pods are immediately terminated without graceful shutdown, potentially causing data loss.

The 'denied: requested access to the resource is denied' error occurs when Docker cannot authenticate or authorize access to a container registry. This typically happens when pushing images without proper tagging, missing authentication, or insufficient permissions on the target repository.

The 'container name is already in use' error occurs when you try to create a new Docker container with a name that's already assigned to an existing container (even if stopped). Remove the old container, rename it, or use a different name for the new one.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

The "Failed PreStop Hook" error occurs when the PreStop lifecycle hook times out or fails during pod termination. PreStop hooks run before SIGTERM to allow graceful shutdown (connection draining, cleanup), but if they fail, the container is force-killed, causing connection loss and potential data corruption.

The "Memory resource exceeded" error occurs when a pod uses more memory than its limit, causing the kernel to OOMKill (out-of-memory kill) the container. This terminates the pod immediately, disrupting services and data processing. Requires investigating memory leaks and adjusting limits appropriately.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

This error occurs when trying to call revalidateTag() outside of server environments in Next.js. The revalidateTag function is restricted to Server Actions and Route Handlers and cannot be used in Client Components or browser contexts.

This error occurs during native module compilation when the node-addon-api headers can't be found or have compatibility issues. Usually caused by missing include paths or version mismatches.

A failing liveness probe causes Kubernetes to repeatedly restart the container, creating a CrashLoopBackOff. The liveness probe detects if a container is deadlocked or unresponsive and triggers a restart to recover. A bad probe configuration or application issue causes restart loops.

This admission error occurs when ResourceQuota or LimitRange requires containers to specify resource limits. Fix it by adding explicit limits.cpu and limits.memory to your container spec.

This error occurs when npm audit fix can't automatically resolve all security vulnerabilities. Usually because fixes require breaking changes or the vulnerable package hasn't released a patch yet.

A failing readiness probe prevents a pod from receiving traffic. The readiness probe indicates if a container is ready to serve requests. When it fails, the pod is removed from load balancing but the container keeps running, allowing debugging without service disruption.

A failing startup probe prevents a container from ever becoming ready. The startup probe (introduced in Kubernetes 1.18) checks if an application has finished starting up. If it fails consistently, the container is killed and restarted after failureThreshold failures.

Pod emptyDir volume exceeds sizeLimit. Fix by increasing limit, reducing data written, or using persistent volume.

This error occurs when Docker receives an HTML response instead of the expected JSON from a registry. Common causes include network proxies intercepting requests, corporate firewalls, geographic IP blocking, or misconfigured registry URLs.

Git has detected that symbolic references form a loop, where ref A points to ref B, which eventually points back to ref A. This prevents Git from resolving the final target commit.

The 'fatal: A branch named already exists' error occurs when you try to create a branch with a name that already exists in your local repository. Switch to the existing branch, use a different name, or reset the branch to a new starting point.

This error occurs when node-gyp can't find the 'make' build tool. Make is required to orchestrate the compilation of native npm modules.

The "missing script" error occurs when you try to run an npm script that doesn't exist in package.json. Check your script name spelling or add the missing script to package.json.
