Common Issues

Containers failing to start

# Check container logs
docker logs <container_name>

# Verify network connectivity
docker network ls | grep azerothcore

# Check port conflicts
ss -tulpn | grep -E "(3784|8215|8081|4201)"

Module not working

# Check if module is enabled in environment
grep MODULE_NAME .env

# Verify module installation
ls storage/modules/

# Check module-specific configuration
ls storage/config/mod_*.conf*

Database connection issues

# Verify MySQL is running and responsive
docker exec ac-mysql mysql -u root -p -e "SELECT 1;"

# Starting with the 2025-11-17 release the import job checks if
# the runtime tables exist before trusting restoration markers. If you see
# "Restoration marker found, but databases are empty - forcing re-import" in
# `docker logs ac-db-import`, just let the container finish; it will automatically
# clear stale markers and replay the latest backup so the services never boot
# against an empty tmpfs volume. See docs/DATABASE_MANAGEMENT.md#restore-safety-checks--sentinels
# for full details.

# Forcing a fresh import (if schema missing/invalid)
# 1. Stop the stack
docker compose down
# 2. Remove the sentinel created after a successful restore (inside the docker volume)
docker run --rm -v mysql-data:/var/lib/mysql-persistent alpine sh -c 'rm -f /var/lib/mysql-persistent/.restore-completed'
# 3. Re-run the import pipeline (either stand-alone or via stage-modules)
docker compose run --rm ac-db-import
#    or
./scripts/bash/stage-modules.sh --yes
#
# See docs/ADVANCED.md#database-hardening for details on the sentinel workflow and why it's required.

**Permission denied writing to local-storage or storage**
```bash
# Reset ownership/permissions on the shared directories
./scripts/bash/repair-storage-permissions.sh

This script reuses the same helper container as the staging workflow to chown storage/, local-storage/, and module metadata paths back to the current host UID/GID so tools like scripts/python/modules.py can regenerate modules.env without manual intervention.

Check database initialization

docker logs ac-db-init docker logs ac-db-import

> Need more context on why the sentinel exists or how the restore-aware SQL stage cooperates with backups? See [docs/ADVANCED.md#database-hardening](ADVANCED.md#database-hardening) for the full architecture notes.

**Worldserver restart loop (duplicate module SQL)**
> After a backup restore the ledger snapshot is synced and `.restore-prestaged` is set so the next `./scripts/bash/stage-modules.sh` run recopies EVERY module SQL file into `/azerothcore/data/sql/updates/*` with deterministic names. Check `docker logs ac-worldserver` to confirm it sees those files; the `updates` table still prevents reapplication, but the files remain on disk so the server never complains about missing history.
```bash
# 1. Inspect the worldserver log for errors like
#    "Duplicate entry ... MODULE_<module_name>_<file>"
docker logs ac-worldserver

# 2. Remove the staged SQL file that keeps replaying:
docker exec ac-worldserver rm /azerothcore/data/sql/updates/<db>/<filename>.sql

# 3. Re-run the staging workflow
./scripts/bash/stage-modules.sh --yes

# 4. Restart the worldserver container
docker compose restart ac-worldserver-playerbots  # or the profile you use

# See docs/DATABASE_MANAGEMENT.md#module-sql-management for details on the workflow.

Legacy backup missing module SQL snapshot

Legacy backups behave the same as new ones now—just rerun ./scripts/bash/stage-modules.sh --yes after a restore and the updater will apply whatever the database still needs.

Source rebuild issues

# Check rebuild logs
docker logs ac-modules | grep -A20 -B5 "rebuild"

# Verify source path exists
ls -la "${STORAGE_PATH_LOCAL:-./local-storage}/source/azerothcore/"

# Force source setup
./scripts/bash/setup-source.sh

Getting Help

1. Check service status: ./status.sh --watch
2. Review logs: docker logs <service-name> -f
3. Verify configuration: Check .env file for proper module toggles
4. Clean deployment: Stop all services and redeploy with ./deploy.sh

Backup and Restoration System

The stack includes an intelligent backup and restoration system:

Automated Backup Schedule

• Hourly backups: Retained for 6 hours (configurable via BACKUP_RETENTION_HOURS)
• Daily backups: Retained for 3 days (configurable via BACKUP_RETENTION_DAYS)
• Automatic cleanup: Old backups removed based on retention policies

Smart Backup Detection

• Multiple format support: Detects daily, hourly, and legacy timestamped backups
• Priority-based selection: Automatically selects the most recent available backup
• Integrity validation: Verifies backup files before attempting restoration

Intelligent Startup Process

• Automatic restoration: Detects and restores from existing backups on startup
• Conditional import: Skips database import when backup restoration succeeds
• Data protection: Prevents overwriting restored data with fresh schema

ExportBackup_YYYYMMDD_HHMMSS/     # Optional manual drop-in under storage/backups/

Place extracted dumps from any `ExportBackup_*` archive inside `storage/backups/` (for automatic detection) or pass the directory directly to `scripts/bash/backup-import.sh --backup-dir <path>` when performing a manual restore.
