[BUG] High CPU usage at random moments

Bắt đầu với issue 536 được liên kết và thu thập log của container trong khi sự cố tái diễn bằng manifest k3s được cung cấp hoặc bản tương đương bằng Docker. Được coi là hoàn tất khi xác định được tác nhân kích hoạt hoặc nguyên nhân có thể tái hiện của mức tăng đột biến CPU và xác thực được một bản sửa lỗi giúp Nextcloud luôn khả dụng.

Is there an existing issue for this?

Current Behavior

Hello, this is a recreation of the very similar bug report link.

I have not seen the errors in the logfiles and unfortunately I can't recheck them. But the symptoms are the same as in the before mentioned tickets just at random times.

I've had it occur twice over the past 5 days, the container just randomly starts using a lot of CPU resources and Nextcloud becomes unavailable. The only thing that seems to resolve it is restarting the container.

Example of the CPU spike on the server in question:

Expected Behavior

No CPU usage spike and application remaining available.

Steps To Reproduce

It seems to be happening randomly.

Environment

OS: 
Ubuntu 24.04.4 LTS

Image: 
lscr.io/linuxserver/nextcloud:33.0.3-ls428

Environment:
k3s (previously experienced the exact configuration in docker as well)

CPU architecture

x86-64

Docker creation

k3s manifest:
: apps/v1
kind: Deployment
metadata:
  name: nextcloud
  namespace: cloud
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nextcloud
  template:
    metadata:
      labels:
        app: nextcloud
    spec:
      containers:
        - name: nextcloud
          image: lscr.io/linuxserver/nextcloud:33.0.3-ls428
          ports:
            - containerPort: 80
          envFrom:
            - secretRef:
                name: cloud-nextcloud
          volumeMounts:
            - name: config
              mountPath: /config
            - name: custom-apps
              mountPath: /app/www/public/custom_apps
            - name: documents
              mountPath: /documents
            - name: pictures
              mountPath: /pictures
            - name: games
              mountPath: /games
            - name: it
              mountPath: /IT
            - name: ebooks
              mountPath: /ebooks
            - name: data
              mountPath: /data


Which is the k3s equivalent of this docker-compose snippet:

  nextcloud:
    image: lscr.io/linuxserver/nextcloud:33.0.3-ls428
    healthcheck:
      test: ["CMD", "curl", "https://wolkje.heijlond.com/index.php/login"]
      timeout: 2s
      interval: 30s
      retries: 1
    environment:
      - PUID=2008
      - PGID=2008
      - TZ=Europe/London
    depends_on:
      - redis
    volumes:
<same mounts>

Container logs

I am working on a way of saving logs to be able to check/paste them. But the previous bug report linked contains logs etc.
