Eventually it reboots every ~25 days with not minidumps or messages in logs. The suspicion was the motherboard and it had been replac= ed by Dell before Xmas so it helped to keep the server running for more then 40 days and then it happen again, and than again in less than 2 days. Yesterday the server stopped responding and after quick glance at iDRAC vir= tual console it reveal the panic screen, see attached screenshot. Unfortunately= I failed to scroll the screen up because of iDRAC virtual console. The swap is 24Gb and Dumping stalled for 10-15 so I had to cold reboot beca= use of no actions. Any ideas if it a hardware or software issue? The system has been upgraded to 11.3-RELEASE-p6 recently. It is Dell R540 = with 128Gb RAM, Dell BOSS NVME RAID0, H730P raid controller with 12 JBOD disks += HBA connected MD1400 via multipath 12 disks. 2 VDEVs ZFS pool, the system is on UFS partition on M.2/BOSS flash disk. /boot/device.hints: hw.mfi.mrsas_enable=3D"1" /boot/loader.conf.local: vm.kmem_size_max=3D130000000000 vm.kmem_size=3D130000000000 vfs.zfs.arc_max=3D128000000000 vm.pmap.pti=3D0 hw.ibrs_disable=3D1 hw.spec_store_bypass_disable=3D1 geom_multipath_load=3D"YES" The system is 100% NAS with samba 4.10, so jails or VMs or active users. Appreciate any ideas how to debug or diagnose the issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
