The transaction log for database '' is full due to 'AVAILABILITY_REPLICA'. [SQLSTATE 42000] (Error 9002). The step failed. SQL 2014

I have noticed that our SQL jobs are failing due to this error.


Message
Executed as user: ''. The transaction log for database '' is full due to 'AVAILABILITY_REPLICA'. [SQLSTATE 42000] (Error 9002).  The step failed.

Below is the SQL configuration :

SQL version is 2014
One Primary and one secondary replicas
Recovery mode is full
Transaction Log file is set to auto grow with limited size.

I have verified the transaction log backups and those were running fine. Not sure why the transaction log was full and this issue I see first time in my environment.

Below queries help to see the Alwayson status, also dashboard gives the same details.

select a.*, b.name

from sys.dm_hadr_database_replica_states a

LEFT JOIN sys.databases b ON a.database_id = b.database_id

Fix: As the always on is not in sync I have taken the database out of always on shrink the database files and add it back to always on. Used below syntax to shrink the databases.

I have explained removing and adding back databases in to Alwayson in another post.

USE AdventureWorks2012;  
GO  
-- Truncate the log by changing the database recovery model to SIMPLE.  
ALTER DATABASE AdventureWorks2012  
SET RECOVERY SIMPLE;  
GO  
-- Shrink the truncated log file to 1 MB.  
DBCC SHRINKFILE (AdventureWorks2012_Log, 1);  
GO  
-- Reset the database recovery model.  
ALTER DATABASE AdventureWorks2012  
SET RECOVERY FULL;  
GO
