Hi, We are new users of Proxmox with CEPH which works fine as of now but we have a strange problem. Once in a few days the whole proxmox management server we have freezes completely and does nothing anymore. The servers are SuperMicro servers and have IPMI. When we check IPMI it wont accept input anymore as well, i have to completely reboot it in order to make it work again until it freezes again, i havent been able to find a pattern yet so it does it completely random. We also have 3 monitor servers with exact the same hardware and configuration and these don't freeze at all. Also atop logs until the time it freezes, but we don't see any significant proces running other then what was already running. Any idea's/ tricks we can do to fix this? The ceph/proxmox configuration is still in a test stadium so it is not urgent, but we like it to work so we can use the full function of the proxmox/ceph environment.
