</code></pre>
<h2 id="troubleshooting">🔧 Troubleshooting</h2>
<h3>Server Won't Start</h3>
<h4>Check Server Logs</h4>
<pre><code># View recent log entries
tail -f server.log
# Or check system logs
journalctl -u gameserver -f
</code></pre>
<h4>Port Already in Use</h4>
<pre><code># Find what's using the port
sudo lsof -i :[PORT]
sudo netstat -tulpn | grep [PORT]
# Kill the process or change server port
</code></pre>
<h4>Missing Dependencies</h4>
<p>Ensure all required dependencies are installed. Check the error messages for missing libraries or packages.</p>
<h3>Connection Issues</h3>
<h4>Can't Connect to Server</h4>
<ol>
<li><strong>Verify server is running:</strong> <code>ps aux | grep server</code></li>
<li><strong>Check port is listening:</strong> <code>netstat -an | grep [PORT]</code></li>
<li><strong>Verify firewall rules</strong> (see Ports section above)</li>
<li><strong>Check server IP:</strong> Use external IP, not localhost</li>
<li><strong>Router/NAT:</strong> Ensure port forwarding is configured</li>
</ol>
<h4>High Latency/Lag</h4>
<ul>
<li><strong>Missing Beta Folder:</strong> Ensure <code style="background: #0f172a; padding: 2px 6px; border-radius: 3px; color: #a5b4fc;">Expansion\beta</code> exists for DayZ</li>
<li><strong>Port Conflicts:</strong> Check if 2302 is already in use</li>
<li><strong>Config Errors:</strong> Validate server.cfg syntax (semicolons required)</li>
<li>Check server resource usage (CPU, RAM, disk I/O)</li>
<li>Verify network bandwidth is adequate</li>
<li>Consider server location relative to players</li>
<li>Check for background processes consuming resources</li>
</ul>
<h3>Players Can't Join</h3>
<ul>
<li>Verify firewall allows UDP 2302-2305</li>
<li>Check mod versions match between server and clients</li>
<li>Ensure BattlEye is enabled if required</li>
</ul>
<h3>Performance Issues</h3>
<h3>DayZ Mod Issues</h3>
<ul>
<li><strong>Database connection:</strong> MySQL required for DayZ Epoch/Overpoch</li>
<li><strong>HiveExt errors:</strong> Check <code style="background: #0f172a; padding: 2px 6px; border-radius: 3px; color: #a5b4fc;">@DayZ_Epoch\HiveExt.ini</code> configuration</li>
<li><strong>Loot not spawning:</strong> Verify mission file and database tables</li>
</ul>
<h4>Server Lag</h4>
<ol>
<li><strong>Monitor resources:</strong> Use <code>htop</code> or <code>top</code></li>
<li><strong>Check disk I/O:</strong> Use <code>iotop</code></li>
<li><strong>Review server logs</strong> for errors or warnings</li>
<li><strong>Reduce player count</strong> or increase server resources</li>
<li><strong>Optimize configuration</strong> based on server capacity</li>
</ol>
<h4>Memory Leaks</h4>
<pre><code># Monitor memory usage
free -h
top -p $(pgrep -f server)
# Restart server regularly via cron if needed
0 4 * * * /home/gameserver/restart.sh
</code></pre>
<h2 id="performance">Performance Optimization</h2>
<h3>Server.cfg Performance Settings</h3>
<pre><code>MaxMsgSend = 256;
MaxSizeGuaranteed = 512;
MaxSizeNonguaranteed = 256;
MinBandwidth = 131072;
MaxBandwidth = 10000000000;
MinErrorToSend = 0.001;
MaxCustomFileSize = 160000;</code></pre>
<h3>Hardware Recommendations</h3>
<h3>Server Tuning</h3>
<ul>
<li><strong>CPU:</strong> 2-4 cores, 3.0+ GHz</li>
<li><strong>RAM:</strong> 4-8 GB minimum</li>
<li><strong>Storage:</strong> HDD acceptable, SSD preferred</li>
<li><strong>Network:</strong> 50+ Mbps</li>
<li><strong>CPU:</strong> Ensure adequate CPU allocation; most game servers are single-threaded</li>
<li><strong>RAM:</strong> Allocate sufficient memory; monitor usage and adjust as needed</li>
<li><strong>Disk:</strong> Use SSD storage for better I/O performance</li>
<li><strong>Network:</strong> Ensure stable, low-latency connection</li>
