Hi, starting from 31/1, I started seeing below logs in 4 of my VMs (out of total 40).
Jan 31 14:08:07 web-dev-public dhclient[1185]: DHCPREQUEST on eth0 to 169.254.169.254 port 67 (xid=0x466eef7d)

........
The log "kernel: Cannot read proc file system: 9 - Bad file descriptor." will then appear continuously with a frequency that the disk space will be used up in few days
I've tried to reboot the VMs but then this will appear again after a day or so.
Those 4 VMs are serving different applications and from the first line of the log, it should be receiving some commands from metadata.google.internal (169.254.169.254) to start with.
All these happens at 31/1 around 12pm(+8).
The VMs are all "CentOS release 6.9 (Final)".
Please help as some VMs are hosting services for our client and I cannot always reboot them.
Thanks a lot.
