    Hello,

    I just got the notification that the turn service ran out of memory while there was no user activity on the server. How do I find out what was wrong? Maybe some memory leak in the service?

    Best Regards,

      Have you checked the logs and also the system information screen?

        One thing to consider here, is that the memory values set in Cloudron are just the upper limits. This is rather unrelated to your actual available memory on the server. So setting high limits will eventually lead to the system killing processes to free up actual physical memory. Maybe if you have overprovisioned your system, the kernel decided to kill turn?

          @nebulon said in The turn service ran out of memory:

          Maybe if you have overprovisioned your system, the kernel decided to kill turn?

          Want to re-iterate this... The OOM Killer of the kernel will randomly kill processes when it needs memory for a process. So, sometimes it will say turn ran out of memory even if you never used turn because it killed turn.

          You can look into the dmesg output, I think you will find some oom info there.

            In dmesg I don't see relevant-looking memory errors like out of RAM. I checked /var/log/kern.log then and I just see tons of package drops (likely from firewall/fail2ban).

            Regarding OOM killer: I doubt it. There was no user activity and according to system info page, there's plenty of free RAM for the last 7 days:

            I just noticed turn is again at 99 % RAM.

              I just checked the error log of turn now (before it was nearly completely empty, likely due to reboot/kill of app) and it shows tons of errors (just a few of 35k lines):

                @warg are you using the apps that use turn ?

                Tried searching for these error messages from coturn but I am not seeing getting any leads so far.

                  I never heard of turn protocol/daemon before so I don't know if and which app uses it internally. Actively (= I'm aware of it): Nope. These apps are installed on my Cloudron v7.5.0:

                    I just rebooted the server to apply kernel updates from livepatching and I see errors like this from the startup (I enabled IPv6 on Cloudron short-term but I'm not sure it's relevant for this issue):

                    Looks there's some IPv6 IP address binding issue and a max file or socket limit reached error.

                      Interesting. I had this recently, too. Memory allowance seems to be about 200% more than used. Seems to have righted itself, so just noting in case relevant and others noticed the same recently, too. Only happened once for as long as I can remember, so perhaps nothing, but noting just because occasional things can be hard to understand without evidence and reproducibility.

                        The critical errors with invalid arguments doesn't come up anymore. I think this came up from some Ubuntu Livepatching being done + missing reboot afterwards. Didn't occur the last days and for extra safety I just updated all packages on the server now. Nothing broke (although it's not suggested to do that) and I will see if issue occurs again.

                          hopefully critical components like docker were not updated then, since this will eventually break. Make sure to have full backups.

                            Thanks for the hint. I accepted that it might break. So far there were just OS-related components updated and DB-stuff. At the moment I saw no critical errors in the apps and they do work. Cloudron works fine as well at the moment. I also restarted the server to see if somethings breaks on full reload. So far, everything is fine and docker-related stuff wasn't updated.

                              Nope, issue was not related to livepatching it seems. Issue just occured out of nowhere again:

                              grafik.png

                              Could this be related to malicious clients, e. g. erros created by bots that try turn-specific exploits?

                                @warg said in The turn service ran out of memory:

                                Could this be related to malicious clients, e. g. erros created by bots that try turn-specific exploits?

                                It does seem to be like that.

                                Is anyone else seeing such messages in the turn service logs?
