areas_rules loop crashes repeatedly — make-area never completes on France extract

[theoricher]

Environment

• Image: wiktorn/overpass-api (latest)
• Mode: init
• Extract: france-latest.osm.pbf from openstreetmap.fr
• OVERPASS_META: yes
• OVERPASS_RULES_LOAD: 100
• OVERPASS_SPACE: 25769803776 (24 GB)
• OVERPASS_UPDATE_SLEEP: 86400
• Server RAM: 32 GB

Problem

The areas_rules process starts and processes elements correctly, but always crashes and restarts around 105,000–128,000 elements. This happens indefinitely — make-area never completes a full cycle.

Observed logs

After 0h5m47s: in "make-area", part 0, on line 29. Stack: 0 of 0 105350 of 0
After 0h6m30s: in "make-area", part 0, on line 29. Stack: 0 of 0 123427 of 0
After 0h0m15s: in "make-area", part 0, on line 29. Stack: 0 of 0 1461 of 0  ← restart

The counter resets to ~1400 each time, consistently after reaching 105k–128k elements.

Troubleshooting done

• No OOM kill visible in dmesg
• No error in journalctl
• No FATAL/exited lines in supervisord logs
• OVERPASS_HEALTHCHECK set to exit 0 — rules out healthcheck interference
• OVERPASS_UPDATE_SLEEP set to 86400 — rules out diff updates interrupting
• OVERPASS_SPACE increased from 12 GB to 24 GB — no change
• area(3601403916) returns empty — areas never written to DB
• Same behavior reproduced with Switzerland extract

Expected behavior

areas_rules should complete a full cycle and write areas to the database.

Question

Is there a known relation or element in these extracts that causes make-area to crash?
