    @nebulon Great point about the VPS. I am going to try "monitoring" two different Cloudrons at different VPS providers. Let's see if there is a similar pattern (perhaps something related to Clourdon) or if one Cloudron is having API issues, then that would suggest a VPS provider issue. In any case and on all Cloudrons, I will check the box.log to see if there is something happening on the Cloudron when API issues appear.

    Independent of the API/heartbeat issues, what is your recommendation on managing the swap file and it's size?

      The rough rule here would be, that if the server has limited RAM, then use a larger swap file. If you have plenty of RAM a smaller say 4GB swap for edge cases to increase stability is good.

      What limited RAM means kinda depends on how much apps and which apps you have installed. So this is really hard to say.

      Overall unless you are sure the swapping is the actual bottleneck, I would not dive too much into that and first check other things.

        @nebulon Let me use "vmstat 1" as you suggested and see what is really going on.

          @Jamie_Casper can you give us an example that's more specific?

            @robi I'm pretty sure @jamie_casper is an AI spam bot - as @girish just spotted, all of their posts are innocent enough looking summaries of posts which don't really add anything. IMHO clearly fishing for upvotes so they can come back and post spam links.

            I use Cloudron with Gandi & Hetzner

                  mh...my server has 32GB of RAM and 4GB Swap.
                  While only 16 GB of RAM are used the swap file is almost at 4GB. Is this expected behavior? DOn't have any problems with performance btw.

                    @sponch I noticed the same on my Cloudron, but I would let the experts weigh in on your question.

                      Hello @sponch
                      It depends on your provider how he initializes the Ubuntu system.
                      A good guide is https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/managing_storage_devices/getting-started-with-swap_managing-storage-devices#recommended-system-swap-space_getting-started-with-swap
                      According to the Red Hat guide, 4GB SWAP for a 32GB RAM system is the minimal recommended.
