CLoudlinux has confirmed a kernel bug that requires a reboot of the servers to resolve that is causing unexpected high load and downtimes.  We will be doing the restarts tonight after 10PM EST

P2's restart suffered a unexpected issue which in the end required a second restart to resolve.  I am taking a break from the restarts to settle ticket's and ensure things are stable.

Due to the unexpected issues with p2 I am going to delay further reboots till tomorrow evening to ensure there are no further unexpected issues.

R2 is taking longer as I am being forced to FSCK the server to address orphaned inodes.

R3 is online and r4 does not a restart as it rebooted into the correct kernel with the crash a few days ago.
