Random errors executing SSIS packages through Azure Data Factory
We are facing the following error throughout a big ADF pipeline in many SSIS packages execution tasks:
"Failed to retrieve resource from master. Microsoft.SqlServer.IntegrationServices.Scale.ScaleoutContract.Common.MasterResponseFailedException: Code:300004"
This error is said to be due to either file not accessible or password not valid.
In our case, this is does not apply. Those packages did not undergo any changes whatsoever and are accessible in a Azure Storage resource.
In fact, the same SSIS package may have always succeeded in the past (say, previous months executions) but failing now.
These are random errors we are getting which do not allow us to maintain an automated process. Sometimes some packages fail, other times they succeed and some other packages fail.
May you be able to help please?
Thanks in advance.
