WinBooks on WebSQL performance degradation for WinBooks on Web
For an unknown reason there is a resource exhaustion on our SQL engine of WinBooks on Web.
We set the application in maintenance until it's fixed. The maintenance page will redirect you once the maintenance is ended.
08:45 - an automated sql index maintenance task has gone wild exhausting all resources of the vm.
08:45 - the task has been stopped, resources are released.
08:50 - the maintenance is removed
After analyzing our monitoring data, the issue has started around 04:30 with a large burst of memory usage, beyond the limit assigned to the SQL engine. We have updated our monitoring system to catch this situation.
