Hello to all,

It's been a while , allmost every morning proxmox host is allmost dead 
and aproximatellz at 7:40 AM  it "wakes up" and continues to work in 
real time.

I saved screen shot on this location (password :  proxtemp)

https://oc1.h-r-z.hr/owncloud/s/mwKpuoiuAnWbRy6


I/O is at 100% and cpu is ver very low ... at 7:25  I had to reboot it 
from kvm/ipmi console because we could wait any more


There is no any scheduled activity that could cause something like that .


I kindly ask for a hint where could I look (logs, ...)  in order to 
diagnose what causes such strange behaviour ?


Thank you very much in advance

and BR

Tonci
