I've got virtual machine CPU usage alarm for VDP this morning. It increased from cca 55% to 95% (there were 15% before VM restoring). Traffic on lo increased to almost 40Mb/s.
I've checked /var/log/messages on VDP and there were a lot of "scsi: killing requests for dead queue" messages around VM restoring and plenty of ssh connections for root from 127.0.0.1 (once in every minute) as well as for admin from eth0 IP (usually four times in a minute) since then - contrary to 2 + 5 connections once a day at 8 AM before. What is going on?
Everi night one to three backup jobs for different VMs fail since then in the adition (no more info in VDP reports). I've set 7 backup jobs for a toatl of 24 VMs.
The same problem again. CPU usage was solved after reboot but heavy traffic on lo persists. I can see RX/TX about 18 Gb after 1 hour uptime. Most of the traffic is to gsan or java/avamar process. What's the reason for using localhost device this way?
