n8n errors / Config

SQLITE_BUSY: database is locked

platform: n8n / category: Config / code: SQLITE_BUSY

Cause

SQLite allows only one writer at a time; concurrent workflow executions writing simultaneously cause SQLITE_BUSY.

Fix

Migrate to PostgreSQL for any instance running concurrent workflows - SQLite is for single-user dev only. If migration must wait, set EXECUTIONS_PROCESS=main to serialise executions. On NAS/Azure file shares, move the SQLite file to local container storage (remote mounts have poor SQLite locking).
