SQLITE_IOERR_GETTEMPPATHERRORTier 2 — Caution⚠️ MEDIUM confidence

I/O error finding a temporary directory

Category: I/O ErrorVersions: 3.0+

🔴 Production Risk Error

Medium — queries requiring temp storage will fail.

What this means

SQLITE_IOERR_GETTEMPPATH (6410) is returned when SQLite cannot determine a writable temporary directory for creating temporary files used during large sorts and intermediate results.

Why it happens

  1. 1TMPDIR / TEMP / TMP environment variables point to a non-existent or non-writable directory.
  2. 2All candidate temporary directories are full or inaccessible.
  3. 3Chroot or sandboxed environment with no accessible temp path.

How to reproduce

Queries requiring temporary storage (large sorts, CREATE INDEX, etc.) when no temp dir is available.

trigger — this will ERROR
import os, sqlite3
os.environ['TMPDIR'] = '/nonexistent'
conn = sqlite3.connect(':memory:')
# Large sort requiring temp file may raise SQLITE_IOERR_GETTEMPPATH
sqlite3.OperationalError: disk I/O error

Fix 1

Why this works

Set TMPDIR / TEMP to a writable directory with sufficient space.

Fix 2

Why this works

Use PRAGMA temp_store = MEMORY to avoid temp files for small result sets.

Fix 3

Why this works

Increase disk space on the temp filesystem.
