Unexpected error in BackendTaskQueues can leave a task unnotified forever,
which prevents further admin commands from completing ("Waiting for n pending
writes")
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: SEQUOIA-1115
URL: https://forge.continuent.org/jira/browse/SEQUOIA-1115
Project: Sequoia
Type: Bug
Components: Core
Versions: sequoia 2.10.10
Reporter: Stephane Giron
Assigned to: Stephane Giron
Priority: Critical
Fix For: sequoia 2.10.11
In BackendTaskQueues, if fetchNextQueryFromBackendTotalOrderQueue fails with a
runtime exception, the task will never be notified of the failure.
This will lead to this well known problem :
2008-07-18 22:38:46,515 INFO controller.virtualdatabase.DB1 Waiting for virtual
database DB1 shutdown
2008-07-18 22:38:46,517 INFO controller.RequestManager.DB1 Suspending activity
for DB1
2008-07-18 22:39:01,517 WARN sequoia.controller.scheduler Waiting for 1 pending
writes
2008-07-18 22:39:31,511 WARN sequoia.controller.scheduler Waiting for 1 pending
writes
where the virtual database will be unable to shutdown properly.
