    Just had another Graphite OOM crash.

    Seems strange seeing it's mostly just me using my Cloudron atm and I'm not really doing anything on it.

    What does Graphite actually do?

    I use Cloudron with Gandi & Hetzner

      @jdaviescoates that service (graphite+collectd) collects the data used in the graphs, like memory usage over time. Given that it causes issues from time to time and also we don't really utilize it well, we are thinking of maybe collecting the data on our own and ditch graphite.

        Thanks

        What would that look like?

            @nebulon Caprover uses Netdata... would that be possible?

              After a server restart, graphite won't start. Reconfig doesn't help.

                I decided to reboot the box for security upgrades (from notifications) and it came up without errors this time.

                    @jdaviescoates how much memory as the limit is set in your case? Also does the server itself have enough free memory to allocate? The settings in Cloudron are only the upper limit, but it may still get killed with oom if there is none available system-wide

                      @nebulon it was at whatever the default is (256MB?) I've now upped it to 512MB to see if that stops it. Plenty of spare RAM on the machine.

                        @nebulon my graphite service has 1.60GB available, still OOM several times a day..
                        the machine where cloudron is running has 30GB available, on average 15 Gb is being used leaving half of the available memory free.

                          All this does not sound right then. Do you see anything suspicious in the graphite logs as such? Like frequent restarts of something or so?

                              I get daily crashes too, with same/similar log messages about cache and draining issues.

                                    @robi here's another one, zoomed at 24h my.armada.digital_ (1).png
                                    Funny thing is I understand it crashes because of memory issues (resulting out of python errors?)
                                    but why/how does Graphite reboot itself ? I mean why fail to reboot for hours and suddenly it back online? why ?

                                      @rmdes nice.. yep not how a health monitored app should behave.

                                      looks like something got stuck for a while then finally failed to get kicked again.

                                          @rmdes are you able to write to me on support@ and give me ssh access, so I can debug this? Would be good understand what's happening here.
