Recent Executions Deleted Randomly

Questions
1

Hello n8n Community,

We’re running n8n in self-hosted mode via Docker Compose and have encountered a serious issue: recent executions are being deleted at random, which prevents me from troubleshooting failed workflows—even though I’ve set:

  • EXECUTIONS_DATA_HARD_DELETE_BUFFER=259200
  • N8N_EXECUTIONS_DATA_PRUNE=true
  • N8N_EXECUTIONS_DATA_MAX_AGE=180

in our Docker file.

Information on my n8n setup

  • n8n version: 1.85.4
  • Database: PostgreSQL
  • EXECUTIONS_PROCESS setting: default
  • Running via: Docker
  • OS: Ubuntu 24.04

Principal execution-related configs

  • EXECUTIONS_DATA_HARD_DELETE_BUFFER=259200
  • N8N_EXECUTIONS_DATA_PRUNE=true
  • N8N_EXECUTIONS_DATA_MAX_AGE=180

This issue is urgent for us—any advice on preventing executions from being deleted or ensuring they persist for debugging would be greatly appreciated. Thank you!

Hello Alaa,

just add the to your env variables

EXECUTIONS_DATA_PRUNE_MAX_COUNT=0

you are probably exceeded the default max count which is 10K
