                            @acebmxer after 3 hours the consumption was slightly rising, so we also deployed the latest rest api patch which is already on master : https://github.com/vatesfr/xen-orchestra/commit/0fef765ce6b4bc96b28e6af9be3d3dba3fa7dc1e

                                @florent was finally able to read the pull
                                /clap ! the fix seems totally legit and consistant with XOA ram ramping up !

                                when will this be officially published ? 😛
                                so we can disable daily reboot of XOA & XO PROXies 😃

                                  that's better but it still grew during the night

                                  (and the process did an aout of memory when I asked for a memory dump)

                                  I reduced the memory allocated to the rest api and will continue monitoring

                                    Hello @bastien-nollet @florent

                                    moving the discussion from this thread (link), to this one as it seems to be tackling the same issue.

                                    This is the RAM usage of my Xen Orchestra instance before applying "fix(rest-api): fix memory-leak on subscription" 7b109c5e-67b5-4994-95f1-4e51815807a0-image.jpeg

                                    Between 04/07 and 04/10 the system was not rebooted. The RAM usage increased step by step as shown in the screenshot caused by backup runs. Each backup run increased RAM usage and it did not go back to where it was before the backup run.

                                    This is the RAM usage after applying said fix via branch "mra-fix-rest-memory-leak".

                                    5a8bfa32-a467-4fa5-b88e-4904b5603a7e-image.jpeg

                                    Between 04/14 and 04/16 the VM was not restarted.
                                    Backup jobs are scheduled to run every day.
                                    RAM usage still increased a bit by each backup run but it seems to be less.
                                    Looks like an improvement (which is great!) but maybe the issue is not fully fixed yet.

                                    I can not fully tell as I need to keep monitoring this a bit more.

                                    I will keep having an eye on this and report back.

                                    Thanks for working on this and best regards.

                                        @MajorP93 I think there are multiple issue for memory . Pillow and acebmxer uses proxy , so the backup memory is handled differently

                                        are you using XO from source or a xoa ? would you be ok to export a memory heap ?

                                          is completely stable since yesterday's patch

                                            @florent Yes I am using XO from sources:

                                            f3222523-abf2-4c99-a9ce-30574cf8615d-image.jpeg

                                            Currently on the branch that @bastien-nollet asked me to test.

                                            Yeah sure I can export a memory heap. Can you give me instructions for that?
                                            Also: currently I have one backup job running. Is it better to take the memory heap snapshot while backup is running or afterwards?

                                            Best regards
