One or many processors which occupying the whole RAM are turning the service inaccessible.
We were obliged to restart the server.
Update(s):
Date: 2011-08-09 13:16:30 UTC All private sql were migrated. We are finalizing the switch.
Date: 2011-08-09 12:13:48 UTC We start the changeovers. An interruption of few minutes is expected.
The manager will be unavailable for the concerned servers, the time of the changeover.
Date: 2011-08-08 21:53:20 UTC Impacted Private SQL server switching seemed to solve the problem.
We are moving the whole remaining Private SQL servers on a new storage for security measurements.
Date: 2011-08-08 13:35:30 UTC The server is up. A corrupted private sql seems to be the cause
of the blocking. We are going to desactivate it and reactivate
on another physical server aside.
Date: 2011-08-08 13:32:37 UTC The server is available again. An intervention is in progress.
