Watching your XtreamUI panel's CPU and RAM usage spike into the red is one of the most stressful things ever. Your streams start to buffer, customers get annoyed, and your whole server feels like it's about to give up. It's a huge pain.
If you're tired of dealing with this, you're in the right place. In this tutorial, we're going to show you exactly how to fix CPU and RAM overload on XtreamUI. We'll walk through some powerful server optimizations you can do right now. Plus, we'll introduce you to a game-changing alternative that makes these problems a thing of the past.
Does this also fix memory leaks and XUI.ONE? Mostly, yes. XUI.ONE is the commercial panel many Xtream UI operators moved to, and it runs on a similar stack (nginx, PHP, MySQL or MariaDB and FFmpeg), so the diagnosis and server tuning below apply to both. Panel-specific paths differ, so check them on your own install.
| What you see | Likely cause | Check | Fix |
|---|---|---|---|
Many ffmpeg processes at the top of top | Transcoding, or dead sources that restart in a loop | ps -C ffmpeg --no-headers | wc -l | Turn off transcoding you do not need, use on-demand for rarely watched channels, fix or remove dead sources |
php-fpm or nginx workers busy | Playlist scans, API abuse, brute-force logins | Requests per second in the panel, top IPs in the nginx access log | Block the IPs, add Fail2Ban for Xtream UI, change exposed ports |
mysqld high CPU or RAM | Huge log and activity tables, missing cleanup crons | mysqladmin processlist, table sizes | Clean streams_sys and old logs, confirm the cleanup crons run |
| RAM climbs until swap, reboot fixes it | Streams RAM disk filling with segments | df -h /home/xtreamcodes/iptv_xtream_codes/streams | Restart stuck streams, clean old segments, restart services |
| Load jumps when a big event starts | Real viewers on one server | Connections vs CPU over time | Move streams to load balancers, add servers |
Log in over SSH and run these read-only checks. They change nothing, so they are safe on a live server:
If FFmpeg dominates, the problem is in your streams. If PHP-FPM or nginx dominates, look at traffic and attacks first. If mysqld dominates, clean the database before touching the kernel settings below.
Before we dive into the fix, it helps to know what's causing the trouble. Often, the default settings on a server are not prepared for the heavy lifting that an IPTV panel requires.
Think of your server like a regular family car. It's great for daily driving, but if you try to haul a giant boat with it, the engine is going to overheat. Your server is trying to haul that boat! The default limits and network settings just aren't designed for thousands of connections, and that's what causes the CPU and RAM overload on your XtreamUI panel.
Alright, let's get our hands dirty and give your server the tune-up it desperately needs. Follow these steps carefully, and you should see a big improvement.
First, a couple of quick checks. It's always a good idea to make sure your system is running smoothly.
Think of ulimit as the number of tasks your server is allowed to juggle at once. On most systems, this number is set way too low for an IPTV server. We're going to give it a massive boost.
First, check your current limit with this command:
If it shows a low number like 1024, it's time to increase it. Open the limits configuration file:
Scroll to the very bottom and add these lines:
Now save the file and close it.
Next, we're going to optimize your server's network traffic. The sysctl.conf file is like the main control board for your server's network. We're going to tweak the settings to handle a huge amount of traffic without breaking a sweat, kind of like widening a highway to prevent traffic jams.
Open the file to edit it:
Scroll to the bottom and paste in all of these settings:
Save and close the file. Now, apply the changes with this command:
Before you paste: copy the original file first (cp /etc/sysctl.conf /etc/sysctl.conf.bak). These values are aggressive and tuned for busy streaming servers; if sysctl -p reports an error for a line, or the server behaves worse, remove that line or restore the backup.
The final step is to reboot your server to make sure all the new settings are active. Once it's back online, you can run the check commands again to verify everything worked:
This should now show 500000.
The standard Xtream UI installer mounts /home/xtreamcodes/iptv_xtream_codes/streams as a RAM disk (tmpfs) sized at 90% of server memory, plus a smaller RAM disk for tmp. Live segments are written there. When a stream hangs or crashes, its old segments can stay behind, and the RAM disk slowly eats the memory your PHP and MySQL processes need. That looks exactly like a memory leak.
df -h /home/xtreamcodes/iptv_xtream_codes/streams/home/xtreamcodes/iptv_xtream_codes/start_services.shCheck before you tune. In the nginx access log, count requests per IP: awk '{print $1}' access.log | sort | uniq -c | sort -rn | head. A handful of IPs with thousands of hits, or many failed logins, is a flood, not real viewers. Block them at the firewall and add Fail2Ban. On the Xtream-Masters panel the Servers page shows requests per second directly: under 500 on the main server is normal traffic, 500 or more is almost always an attack, and on a load balancer 200 or more suggests one (source: ottpanel.tv/faqs).
Yes. Xtream UI links /usr/bin/ffmpeg to the old FFmpeg build bundled with the panel, and that build is not maintained. On the Xtream-Masters panel, FFmpeg v7 is the supported build for Ubuntu 20.04, 22.04, 24.04 and 26.04, and FFmpeg v5 is used only on Ubuntu 18.04 or older; when every stream on one load balancer goes down, switching that balancer to FFmpeg v7 is the documented fix.
Still on an old Ubuntu release? See the Xtream UI install guide for which version runs where, and Xtream UI on Ubuntu 24.04 for the community-build route. Seeing HTTP 500 errors instead of load? Read fix Xtream UI 500 error.
Those manual fixes can stabilize an Xtream UI or XUI.ONE panel. If you are tired of putting out fires on unmaintained software, the Xtream-Masters OTT panel is a maintained alternative: it runs on Ubuntu 18.04 to 26.04, spreads streams over unlimited load balancers on one license, and migrates your Xtream UI database.
Without stable software, it's not just a wasting time, but also a waste of money on servers, streaming, and potential growth.

Usually one of four things: too many FFmpeg processes (transcoding or sources that keep restarting), PHP-FPM flooded by playlist scans or brute-force requests, a bloated MySQL database, or an attack. Run top sorted by CPU to see which process is responsible, then apply the matching fix from the table on this page.
XUI.ONE runs on a similar stack to Xtream UI (nginx, PHP, MySQL or MariaDB and FFmpeg), so the same checks apply: find the busiest process, stop transcoding you do not need, block flooding IPs, clean large log tables, then raise file limits and tune sysctl as shown in the steps.
Most "memory leaks" on Xtream UI are the streams folder, a RAM disk that the installer sizes at 90% of server memory, filling with segments from stuck or crashed streams. Check it with df -h, restart the stuck streams, clean old segments and restart services. Steady growth after that points to PHP or MySQL settings.
Not always, but check it first. Look at requests per second and at the IP addresses in the nginx access log. Thousands of requests from a few IPs, or many failed logins, mean a flood or brute-force attempt, and blocking those IPs lowers CPU at once. Steady load that follows viewer numbers is real usage.
