There was a problem with the automatic backup service. Fixed here http://status.ovh.net/?do=details&id=12599

The issues is due to the insufficient memory and cpu assigned to the VPS.

Solution for "hung_task_timeout_secs" change vm.dirty_ratio and vm.dirty_backgroud_ratio parameter on the server using the following commands:

sysctl -w vm.dirty_ratio=10
sysctl -w vm.dirty_background_ratio=5
sysctl -p

To Make it permanent ADD 2 lines at the bottom of /etc/sysctl.conf file and reboot the server.

vm.dirty_background_ratio = 5
vm.dirty_ratio = 10

Try this and update us if you have any queries or concerns.

There are 3 days that my VPS becomes unstable just after the ovh automated backup. When logging in KVM the following message appears:


Only after restarting it back to normal.
