      Hi all

      First time with a competition's setup...
      And a big step forward for me

      HGR-SAP-3 :
      2x480 SSD Sata Soft RAID1
      12x3.84To SSD SAS Hard RAID50
      96 CPU : 2 x Intel Xeon Gold 6248R - 24c/48t - 3 GHz/4 GHz
      768Go RAM

      PCI devices :
      4x MT27800 Family [ConnectX-5] (Mellanox Technologies ConnectX-5 EN network interface card for OCP2.0, Type 1, with host management, 25GbE dual-port SFP28, PCIe3.0 x8, no bracket Halogen free ; MCX542B-ACAN)
      RAID bus controller MegaRAID SAS-3 3324 [Intruder]

      VM in production :
      14 VM
      56 CPU
      339 Gib
      6.8 TiB (because of ZFS)
      100% Windows environement

      All VM are on my RAID50 ZFS disk
      (zpool create -o ashift=12 -m // zfs set dedup=on //zfs set atime=off /zfs set sync=disabled (I remove the name ))

      xcp-ng 8.3 all patch on and 16 GiB (beacause using nfs SR)

      Fist time for me with xcp-ng 8.3 and zfs I made a pool and one host in this pool bond network card

      I dont't have a good practice for saving my VM, I made replication

      If I don't do any save, xcp-ng is ok

      I have a 400 Gb Orphan VDIs

      When I made a replication of the VM this weekend the system freeze
      I'm connect whith the IPMI and have this message (translation of my screenshot) :

[***] A start job is running for dev-disk-by\x2dlabel-root\x2dxrdbfu.device (1d 15h 49min 32s no limit)

      I don't see the CPU0: Unexpected LVT thermal interrupt! in all the xcp-ng log

      I have all the log whith me
      I power Off / On for reboot xcp-ng (8am)

      But whith all VM autostart "On" and an automatic task of "Garbage Collector for SR"
      I have a lot off trouble
      VM very slow and garbage task on a same time
      xcp-ng freeze and crash with or not reboot 4 time between 12 and 13h
      after second or third reboot I have time to disable the autostart of all VM and reboot VM one by one
      I disable the backup task and xcp-ng don't reboot since monday afternoon

      It's my second server by ovh the first one have other bug so I can change it but in fact I have the same problem of freeze and reboot

      I'm just sure of the result (freeze and or crash) but not why it the beginning
      The ultimate consequence was an out of memory of xcp-ng

      I have hundred Mo of log if you want something more
      Perhaps I'm wrong and it's a hardare incompatibility ? (network card, hard raid...)
      I have zabbix snmp probe

      Thank's
