I have an SSIS package deployed to the SSIS catalog on my Data warehouse which has run successfully for months. The package is executed by a SQL agent job.
Now it fails intermittently with the following error:
SQL agent history says says:
Date 6/12/2015 6:00:00 a.m. Log Job History (PBI) Step ID 1 Server DEV-DW Job Name PBI Step Name Customer DETL Duration 00:00:12 Sql Severity 16 Sql Message ID 27195 Operator Emailed Operator Net sent Operator Paged Retries Attempted 0 Message Executed as user: \. The operation failed because the execution timed out. [SQLSTATE 42000] (Error 27195). The step failed.
In the SQL logs it says:
Unsafe assembly 'microsoft.sqlserver.integrationservices.server, version=126.96.36.199, culture=neutral, publickeytoken=xxxxxxxxxxxx, processorarchitecture=msil' loaded into appdomain 73 (SSISDB.dbo[runtime].103).
- Why would it only fail sometimes?
- Why is it failing now?
- What is the root cause?
- How can I fix this?
Running SQL 2012 SP2 (11.0.5343) on Win 2008 R2 Standard SP1 on VMWare.
Edit: Updated to SQL 2012 SP3 (11.0.6020).
Edit: have added more context and clarified.
Following suggestion from @TheGameisWar, I queried ssisdb
SELECT * FROM [SSISDB].[catalog].[event_messages] WHERE event_name = 'OnError'
Returns no error messages for that date.
