Update 28th Oct @ 10:10: This issue has been tracked back to a memory leak in the version of virtuozzo on this machine. It will have to be upgraded in the near future. This morning we rebooted the physical server that both of the VMs below reside on, this appears to have stabilised the system somewhat so we're happy with it's performance at the moment.

Rest assured that we're working on this as a top priority and that we're monitoring it very closely. The main cause was too busy sites hammering the MySQL servers which uncovered the memory leak that we mentioned above. We'll move one of these DBs to a newer server today which should mean that this node will be more stable until we can schedule a maintenance window where we can run the updates to the VM platform.

The following database server is having issues again this morning:

mysql637.cp.blacknight.com
mysql637int.cp.blacknight.com

and

mysql640.cp.blacknight.com
mysql640int.cp.blacknight.com

Our engineers are working on this and have been working on this since the server first started to show problems.  We hope to have this resolved as soon as possible.

I have asked our engineers to update this status post with more information as soon as they can.
