[pve-devel] need help to debug random host freeze on multiple hosts

[Alexandre DERUMIER]

I'm around 60-70% load on this quad opteron platforms. 

>>You have check too, that 60-70 % are normal use? 
Well, yes, Xmas period, so I have more traffic than usual.

>>You have Log-Files with 0 Bytes? (on host and in containers) 
No, all is fine

>>You have Hacking-Attacks from and to your servers? 
Everyday ;) But on the guests vms, not the host.
I thinked of a potential CVE in qemu and kvm, but even with updated qemu (2.2) or kvm host module with last rhe7.1 beta kernel,
it's crashing


>>Before freezing: 
>>
>>Is your memory consumption is going down? (htop) 
no
>>Scheduled/Running Prozesses going up? (htop) 
no
>>Disc-IO is going up? (atop) 
no



I really don't see nothing special when crash occur :(

You have check too, that 60-70 % are normal use?

Is your memory consumption is going down? (htop) 
Scheduled/Running Prozesses going up? (htop) 
Disc-IO is going up? (atop)
