    This looks ok and good enough to me. I am always a bit unsure about disk I/O measurements and also if this is the root cause here at all, but anyways maybe you can do some sanity check with hdparm -t /dev/vda1 (replace /dev/vda1 with you main disk partition)

    It should be somewhere above 500MB/s at least on provider with SSD in my experience.

      FYI, CPU usage is now stable and around 13%, more or less since Contabo did, and I quote their email, a "technical adjustement".

      You can clearly see on that monthly CPU chart, how it evolved (granted it's early days, but still):

      Not only this, but the dashboard now loads nearly instantly whereas beforehand, it could take up to 30 seconds.

      Taking into account previous random issues with cheaper Contabo VPS in the past, I tend to think the issue was from Contabo from the start.

        nice to see it resolved outside of Cloudron.

        If you want a similarly sized and less expensive system, I can share an invite link for ssd nodes that's been working well for us.

          @robi Yes please. 🙂

          I also think next time I encounter a stability issue, I'll explore the provider angle sooner, maybe by replicating it elsewhere the same stack.

            Hello all, I've a similar problem and I want to ask you what can be the source causes coming from provider.

            I'm running a Cloudron instance on a bare metal machine on Hetzner, and I get constantly CPU under 40-50%.

            Let me know if I have to open a new post or keep continuing on this.

              @p44 is the htop output similar or some other app/process causing the cpu usage?

                Hello @nebulon,

                I did systemd-cgtop and the result is this:

                alt text

                Then, from Cloudron control panel, the output is this:

                alt text

                Just few months ago, CPU it was stable to 1-2% in the not working hours time.

                Now it seems to be little bit increased, so I was asking myself if this problem was related to Cloudron or to provider (Hetzner).

                  I seem to be having a similar issue. None of the apps in cloudron are using enough cpu to even show up here, but I am constantly needing to reboot the cloudron vm to get the cpu usage to drop back down to normal levels.

                  Not sure if you can tell from the graph, but I've needed to reboot it 3 times in the last month because apps become unresponsive whenever this happens.

                  htop won't help now because it was just rebooted yesterday and everything seems to be running smoothly.
                  Does anyone have any suggestions on how to find out why this is happening, or how to find out the cause?

                      @jonslab just to double check, so the server has 12 cores?

                          @p44 per your cgtop output something is using 47.4%. Are you able to identify the process using top or htop?
