+# Common Issue Resolutions
+
+Quick fixes for frequently encountered claude-mem problems.
+
+## Issue: Nothing is Remembered After `/clear` {#nothing-remembered}
+
+**Symptoms:**
+- Data doesn't persist across sessions
+- Context is empty after `/clear`
+- Search returns no results for past work
+
+**Root cause:** Sessions are marked complete but data should persist. This suggests:
+- Worker not processing observations
+- Database not being written to
+- Context hook not reading from database
+
+**Fix:**
+1. Verify worker is running:
+   ```bash
+   pm2 jlist | grep claude-mem-worker
+   ```
+
+2. Check database has recent observations:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations WHERE created_at > datetime('now', '-1 day');"
+   ```
+
+3. Restart worker and start new session:
+   ```bash
+   pm2 restart claude-mem-worker
+   ```
+
+4. Create a test observation: `/skill version-bump` then cancel
+
+5. Check if observation appears in viewer:
+   ```bash
+   open http://127.0.0.1:37777
+   # Or manually check database:
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT * FROM observations ORDER BY created_at DESC LIMIT 1;"
+   ```
+
+## Issue: Viewer Empty After Every Claude Restart {#viewer-empty}
+
+**Symptoms:**
+- Viewer shows no data at http://127.0.0.1:37777
+- Stats endpoint returns all zeros
+- Database appears empty in UI
+
+**Root cause:**
+- Database being recreated on startup (shouldn't happen)
+- Worker reading from wrong database location
+- Database permissions issue
+
+**Fix:**
+1. Check database file exists and has data:
+   ```bash
+   ls -lh ~/.claude-mem/claude-mem.db
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+   ```
+
+2. Check file permissions:
+   ```bash
+   ls -la ~/.claude-mem/claude-mem.db
+   # Should be readable/writable by your user
+   ```
+
+3. Verify worker is using correct database path in logs:
+   ```bash
+   pm2 logs claude-mem-worker --lines 50 --nostream | grep "Database"
+   ```
+
+4. Test viewer connection manually:
+   ```bash
+   curl -s http://127.0.0.1:37777/api/stats
+   # Should show non-zero counts if data exists
+   ```
+
+## Issue: Old Memory in Claude {#old-memory}
+
+**Symptoms:**
+- Context contains outdated observations
+- Irrelevant past work appearing in sessions
+- Context feels stale
+
+**Root cause:** Context hook injecting stale observations
+
+**Fix:**
+1. Check the observation count setting:
+   ```bash
+   grep CLAUDE_MEM_CONTEXT_OBSERVATIONS ~/.claude/settings.json
+   ```
+
+2. Default is 50 observations - you can adjust this:
+   ```json
+   {
+     "env": {
+       "CLAUDE_MEM_CONTEXT_OBSERVATIONS": "25"
+     }
+   }
+   ```
+
+3. Check database for actual observation dates:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT created_at, project, title FROM observations ORDER BY created_at DESC LIMIT 10;"
+   ```
+
+4. Consider filtering by project if working on multiple codebases
+
+## Issue: Worker Not Starting {#worker-not-starting}
+
+**Symptoms:**
+- PM2 shows worker as "stopped" or "errored"
+- Health check fails
+- Viewer not accessible
+
+**Root cause:**
+- Port already in use
+- PM2 not installed or not in PATH
+- Missing dependencies
+
+**Fix:**
+1. Try manual worker start to see error:
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   node plugin/scripts/worker-service.cjs
+   # Should start server on port 37777 or show error
+   ```
+
+2. If port in use, change it:
+   ```bash
+   mkdir -p ~/.claude-mem
+   echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+   ```
+
+3. If dependencies missing:
+   ```bash
+   cd ~/.claude/plugins/marketplaces/thedotmack/
+   npm install
+   pm2 start ecosystem.config.cjs
+   ```
+
+## Issue: Search Results Empty
+
+**Symptoms:**
+- Search skill returns no results
+- API endpoints return empty arrays
+- Know there's data but can't find it
+
+**Root cause:**
+- FTS5 tables not synchronized
+- Wrong project filter
+- Database not being queried correctly
+
+**Fix:**
+1. Check if observations exist in database:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations;"
+   ```
+
+2. Check FTS5 table sync:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "SELECT COUNT(*) FROM observations_fts;"
+   # Should match observation count
+   ```
+
+3. Try search via API directly:
+   ```bash
+   curl "http://127.0.0.1:37777/api/search/observations?q=test&format=index"
+   ```
+
+4. If FTS5 out of sync, restart worker (triggers reindex):
+   ```bash
+   pm2 restart claude-mem-worker
+   ```
+
+## Issue: Port Conflicts
+
+**Symptoms:**
+- Worker won't start
+- Error: "EADDRINUSE: address already in use"
+- Health check fails
+
+**Fix:**
+1. Check what's using port 37777:
+   ```bash
+   lsof -i :37777
+   ```
+
+2. Either kill the conflicting process or change claude-mem port:
+   ```bash
+   mkdir -p ~/.claude-mem
+   echo '{"env":{"CLAUDE_MEM_WORKER_PORT":"37778"}}' > ~/.claude-mem/settings.json
+   pm2 restart claude-mem-worker
+   ```
+
+## Issue: Database Corrupted
+
+**Symptoms:**
+- SQLite errors in logs
+- Worker crashes on startup
+- Queries fail
+
+**Fix:**
+1. Backup the database:
+   ```bash
+   cp ~/.claude-mem/claude-mem.db ~/.claude-mem/claude-mem.db.backup
+   ```
+
+2. Try to repair:
+   ```bash
+   sqlite3 ~/.claude-mem/claude-mem.db "PRAGMA integrity_check;"
+   ```
+
+3. If repair fails, recreate (loses data):
+   ```bash
+   rm ~/.claude-mem/claude-mem.db
+   pm2 restart claude-mem-worker
+   # Worker will create new database
+   ```
+
+## Prevention Tips
+
+**Keep claude-mem healthy:**
+- Regularly check viewer UI to see if observations are being captured
+- Monitor database size (shouldn't grow unbounded)
+- Update plugin when new versions are released
+- Keep Claude Code updated
+
+**Performance tuning:**
+- Adjust `CLAUDE_MEM_CONTEXT_OBSERVATIONS` if context is too large/small
+- Use `/clear` to mark sessions complete and start fresh
+- Use search skill to query specific memories instead of loading everything
