emptyDir volume size limit exceeded, pod evicted

What this error means

emptyDir volumes can fill up quickly if applications write logs or temporary files. When limit is exceeded, pod is evicted.

Typical symptoms

  • Pod OOMKilled or evicted
  • Container status unknown after limit hit
  • Write operations start failing
  • Pod becomes unstable

Common causes

  1. Application writing too much data
  2. sizeLimit set too low
  3. Logs not being rotated
  4. Temporary files accumulating

How to fix "emptyDir volume size limit exceeded, pod evicted"

volumes:
- name: tmp
  emptyDir:
    sizeLimit: 500Mi  # Increased
3Reduce data written

Configure log rotation and cleanup.

4Use persistent volume for large data

Use PVC for data exceeding emptyDir limits.
