keycloak + infinispan getting error - Event object wasn't available in remote cache after event was received. Event key: 09de68ed-b042-4306-97f9-0f420c67e9cb

My cluster has been getting this error and tried googling and this is the closest issue i found. https://github.com/keycloak/keycloak/issues/25322

My setup, keycloak with infinispan backed by postges setup.  After reviewing my cluster setup, I notice that my statefulset created some ghost pod - meaning keycloak CRD states that it is 3 replicas, while my kubernetes statefulset is 6. And yes, some one update the STS manually and causes this issue.

Why is solving this issue is important? Keycloak node will get into a crazy GC collection stage retrying alot of the operation again and again. And your keycloak node becomes really busy and before you know it, your keycloak pod is flagged as 'unhealty'

My fix: I ensure the STS and keycloak replicas are in sync with each other - same replica. 

kubectl edit sts/keycloak -n keycloak-wwnz

And then ensure replica is 5.

vllm : Failed to infer device type

Trying to run vllm without gpu will typicaly lands you into this issue. To resolve this issue: we can use set these both. Setting one does not work for me. So i had to configure both settings below:- 1.  environment variable CUDA_VISIBLE_DEVICES = "" 2. in the command line, change to use device cpu and remove  tensor-parallel-size. For example, python3 -m vllm.entrypoints.openai.api_server --port 8080 --model deepseek-ai/DeepSeek-R1 --device cpu --trust-remote-code --max-model-len 4096" References https://docs.vllm.ai/en/latest/getting_started/troubleshooting.html#failed-to-infer-device-type

gemini cli getting file not defined error

Image
 While trying to run gemini cli on my windows linux subsystem, i bump into this error here - "/Roaming/npm/node_modules/@google/gemini-cli/node_modules/undici/lib/web/webidl/index.js:512 webidl.is.File = webidl.util.MakeTypeAssertion(File)"  "ReferenceError: File is not defined" In Node.js, there’s no built-in File (until very recent Node 20+ with experimental WHATWG APIs). So, unless polyfilled, File is undefined, leading to the ReferenceError. And to resolve this, I had to upgrade to node 22 (might work for node 20) and then I was able to run it.
