Hi All,
A recent bug within the CentOS kernel has caused two of our servers to freeze due to the R1Soft backups. To stop this happening again we have compiled custom kernels which require a reboot to be applied.
We will start rebooting servers at midnight tonight, reboots will be staggered to avoid the DNS cluster going offline and each server will be down for around 10 minutes.
Some servers have not been affected by this kernel bug yet but rather than wait for each server to crash we've applied the patch to prevent extended periods of downtime in the future.
Thanks and Rgds,
Support Team
