Cyberpanel Freezes every 1~2 weeks

Support and Discussion
1

Hello. The server works fine. 0-3% CPU use in idle, 17% RAM usage, all seems fine.

The main problem is that Cyberpanel completly freezes every 1~2 weeks. When freezes, no SSH, all websites are down, webpanel is not loading. Mail server is not connecting. The only solution is restarting the server via VPS panel.

Current Version: 2.3, Build: 4

Current Commit: d65b6b5bcd4e89ce1a0eeb74131f98093e85bb3a

Some help please? The logs seems good.

I’m having the same issue here

I scheduled an auto reboot of the server once a week as temporary solution… other ideas? I’m on ubuntu 22.0.4 LTS with all packages updated.

I have mailscanner. When updated the Ubuntu packages I was not able to receive or send mails. I disabled mailscanner and mail works fine. But mailscanner not working any more. Some perl packages was missing, and I installed them, but not working. Be careful if you update the system to prevent freezes.

Aany other news? Thanks.

It keeps hanging even with an automatic restart all weeks. No hardware issues. All is updated. Some help?

UPDATE: I made a deep debug session. I don’t found nothing relevant excepts in the file:

/usr/local/lsws/logs/stderr.log

“Reached max children process limit: 10, extra: 3, current: 13, busy: 13, please increase LSAPI_CHILDREN.”

So I increased this value and Max connections in LSWS web console

max conn

Hope this solves the issue…

I was having the same thing happen. I spent a great deal of time configuring a new server and moving five sites over. This was because my Linux version on the older server was becoming unsupported soon and I worried about kernel issues. I lost too much time on this. Some sites would go do with a server error showing up in the command line. Had to restart the server. This happened just about every other week, I would get a notice that some of the sites went down. Fun. My solution was to move off of this messy control panel and go back to the basics on a fresh new Alma Linux / Cloud Linux / Immunify 360 server, the way I should have gone in the first place. It just freaking runs and these unexplained issues just go away, period.

Hello @jimhill1000 I manage several servers mostly running the latest cyberpanel version and not a single issue till for almost 4 months now. Most probably a bad website or server configuration.Have a good look and let us know

The problem persists.

Currently I do not have any type of error in the logs. I have a weekly automatic restart scheduled. I updated the entire system as well as the panel. However the server keeps freezing every one or two weeks.

I have asked the VPS provider (SSD nodes) to check that the hardware is fine and it is.

I have requested assistance on the forums and I have even requested assistance from the creator of cyberpanel, offering to pay him for it and I have not received help from anyone.

I have seen that cyberpanel is updated and adds new payment functions, although it has had many bugs to correct for a long time and they are not being worked on.

For example:
It crashes and I don’t know why. It happens to many users as can be seen here in the support forum.

It puts junk entries in DNS zones that cannot be removed. Repeated entries.

It causes problems with email clients, especially thunderbird.

Cumulative backups fail, proper retention cannot be set.

There is no response from support. Not even offering money in exchange.

Customer websites go down.

Google does not see your website and penalizes you.

You invest hours in debugging and achieve nothing.

It gives problems with php versions. The panel shows all versions even if they are not installed and lets you select them. Which causes problems on the server.

The logs show no signs of failure even when the server freezes every week.

I have not done anything to cause it to crash, I have not installed anything strange except the panel following the instructions. And I have only used the panel, nothing more. Doing things that the panel allows.

The best solution will be to generate a backup copy of all websites and databases, migrate email using Thunderbird and purchase a directadmin license.

I trusted cyberpanel, I wanted to find a solution and continue using it, but it has been impossible.

Thanks everybody, greetings. I leave.

Yes, I am leaving as well, before the pain becomes unbearable. I am a highly experienced sysadmin with decades of experience managing multiple hosting and reselling accounts and lots of different systems and technologies, so I know hosting! I am barely moving deep enough in the CyberPanel testing phase, and it is already excruciatingly painful, to say the least.

I am constantly looking for alternatives to WHM/CPANEL, and I was hoping CyberPanel would be one of them, but IT ISN’T!

It is a good piece of software, I can assure everyone. It is flawed because it is an ongoing project, and I understand that, but a couple of major problems other than software bugs render it completely unusable.

  1. Unresponsive Community: For every single error or problem I discovered (literally, I keep track of them), I found numerous entries in the forum with NO SOLUTION. ZERO! NADA! Aside from clues and debates from users like me who work hard to find workarounds, the people who could (should) follow those forums to provide assistance or seek fixes are completely absent. It means that the developers are not paying attention to the community, either because they are sloppy, arrogant, or careless, and the users are orphans of those who could (SHOULD) listen, debug, and fix the issues to make CyberPanel a true reliable product.
  2. The majority of the errors I found have been reported by other users 2 to 4 years ago, and there have been many (MANY) releases since then, but none fixed ANYTHING. I see an active developer community bragging about their new features and accomplishments, but no one (literally no one) is interested in working to fix the problems they created. So, reliability is ZERO!!!
  3. CyberPanel is NOT FREE. I mean, the core is free, but there are numerous hidden charges! From server and infrastructure offers to addon packages, the majority of what is absolutely required for a production hosting panel is systematically missing from the CyberPanel, forcing users to pay for it. Please do not believe that I am unwilling to pay; I AM, and I WAS paying (today I will cancel all subscriptions I created). I pay to support other systems I use, such as PLEX and TrueNAS; I believe in supporting good work. And, for this reason, I AM RUNNING AWAY FROM CYBERPANEL, because the community can be described as anything other than “good work.” This is, by far, the worst open-source community I have ever encountered, and believe me, there are more bad than good open-source communities out there. What is funny is that their selling channels and charging features work flawlessly!

Ultimately, from the most basic things, like impossible-to-connect FTP and broken Posix, to random freezes of the entire system for no reasons whatsoever (and no logs to debug), I cannot rely on something that is flawed on every single corner of it, even if it was for fun, when the ones that could fix it don’t care enough to fix it.

If you are reading it, it is now 2025, and CyberPanel is simply useless for anything. It appears to work, but when you take it for a spin, it literally falls apart, and you won’t find a single hope for any help, just more charges.

SIMPLY RUN FROM IT!!!

Goodbye forever, CyberPanel. I will never even try it in the future because this community demolished any hope of a possible bright future. Why? Read the threads! It will be time well invested! You will see that NOTHING IS SOLVED, EVER!

Do not waste your time! CyberPanel is not worthwhile! Never was, and will never be!
