[SOLVED] VM (centos7) process sporadically ended without helping logs

[fireon]

Hello,

Linux virtu01 4.4.59-1-pve #1 SMP PVE 4.4.59-87

have here an DELL R530 Server with PERC H730 Mini (Integriert) 1024MB Cache. Since some weeks one VM of the server (a Centos7 Mailserver) crashes sporadically. Der are no helping logs in the VM, never. The log is ending... and then you can see the VM is booting. (attached vm-log.png)

But on the Proxmoxserver there seems to be some interessting logs. There is nothing with oomkiller or similar, but an smartmessage:

May 16 08:14:29 srv-virtu01 smartd[2314]: Device: /dev/bus/0 [megaraid_disk_00] [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 80 to 81

Looks like a Problem with the Raidcontroller? Had this problem ever someone?

Thanks for Help.

After changing to LTS-Kernel and give more memory it was working fine.
